The effective target range is 3,000 m (3,300 yd).[4]. iMac vs 20mm Anti-Tank Lahti slow motion Richard Ryan Any donations to the channel to help me hire help and make more videos! O 1163 - O 1163 DEACTIVATED INERT. There was an earlier Type 94 AA gun which used even larger (20x158) ammunition, but this saw very little use before being replaced by the Type 98. SEMAG continued development of the weapon, and in 1924 had produced the SEMAG L, a heavier weapon (43 kg) that fired more powerful 20×100mmRB ammunition at a slightly higher rate of fire, 350 rpm. Consulta los ejemplos de traducción de anti-tank round en las frases, escucha la pronunciación y aprende gramática. It cost 1/5th of the price to produce. May 1, 2013 Ian McCollum Anti-Tank Rifles 44. The RAF Regiment made extensive use of Oerlikon guns in the anti-aircraft role. The Canadian weapons manufacture… To facilitate this, the Oerlikon's chamber is longer than needed to contain the cartridge, and the front-end of the bolt, which is the same diameter as the case, actually enters this extended chamber behind the cartridge before firing. High Explosive, Anti-Tank (HEAT) Unlike the above shells, all of which use kinetic energy to penetrate armor plates, the high explosive, anti-tank (HEAT) shell is a shaped charge. Japanese Type 97 20mm Anti-tank Rifle Japanese Type 97 20mm Anti-tank Rifle. A modern Oerlikon cannon (Oerlikon 20mm/85 KAA) on a Royal Navy warship, "The Machine Gun", Volume4, George M.Chinn., page 12. The propulsion system uses an obturating case base with a semi-combustible cartridge wall. [7], The A4 (formerly E4) variant was under development by General Dynamics Ordnance & Tactical Systems and Alliant Techsystems (ATK)[8] until ATK received a $77 million, three-year contract on 11 July 2011 to develop and qualify the M829A4 Advanced Kinetic Energy (AKE) round for the U.S. Army's M1A2 SEP (System Enhancement Package) Abrams MBT. [4], This unique chamber and bolt design necessitates the use of a characteristically shaped cartridge: the case has straight sides, very little neck, and a rebated rim. Used cartridges are ejected from below the breech. The Solothurn firearms company was owned by the German firm Rheinmetall, who used the Swiss company to manufacture arms which were prohibited for manufacture by any German firm under arms limitations imposed at the end of the First World War. This powerful round was also credited with some anti-tank capability and so came with AP as well as HE projectiles. The contract includes M829A1 and M829A2 rounds. And the FFS, which weighed 39 kg, delivered a high muzzle velocity of 830 m/s at a rate of fire of 470 rpm.[4]. It is a technology improvement over the M829A1. This is a very high quality magazine that has some serious steel in it. The 7.9 kg (17 lb) of JA-19 propellant creates a chamber pressure of 5,600 bars (81,221 psi), which results in a muzzle velocity of 1,575 m/s (5,170 ft/s). T4 automatic gun. This was capable of perforating 40mm of perpendicular armor plate at 100m (a high explosive projectile was also made). Rated 0 out of 5 $ 3,920.00 Add to cart. DEACTIVATED INERT. This gun used a 400-grain (26-gram) charge of IMR 4831 smokeless powder to propel a 2,000-grain (130-gram) projectile at 2,800 feet (850 meters) per second.[5]. And the Imperial Japanese Navy, after evaluating all three guns, ordered developments of the FF and FFL as the Type 99-1 and Type 99-2. Several of the rifles remained in service after World War II serving as an anti-helicopter weapon, while many others were sold to collectors, mostly in the United States. Modeling was designed at the Ballistic Research Laboratory (BRL) at Aberdeen Proving Ground (APG),[1] which was incorporated into the Army Research Laboratory (ARL) in 1992. As a result of its large, powerful ammunition, the gun had a tremendous recoil, and its size made portability difficult. A post WW2 round with a steel caseing. This used a 20×70mmRB cartridge and had a cyclic rate of fire of 300 rpm. Included with sell are 12 unfired brass casings for reloading , Two 10 rd mags with carrier. In 1927 the Oerlikon S was added to the existing product line. Three sizes of gun with their different ammunition and barrel length, but very similar mechanisms, continued to be developed in parallel. This suggests the steel tip is used to defeat the ERA, with the depleted uranium using to complete the penetration through the vehicle's passive armour. These include the use of a special manufacturing process to improve the structural quality of the depleted uranium penetrator. The incorporation of the improvements of the FFS in a new anti-aircraft gun produced, in 1938, the Oerlikon SS. These features will limit the rate of fire of such guns, unless other steps are taken—as in the final model of the Japanese 99 Mark 2. The FF fired a slightly larger cartridge than the AF, 20x72RB, but the major improvement in these weapons was a significant increase in rate of fire. During World War II, twin and quadruple Oerlikon mounts were developed, both for army and for navy use. Different nations and services operated a number of mounting types for the same basic gun. But they and the PIAT were legal to own in those days, ... but a friend's dad was PMST at the USU ROTC unit and he had a Boys .55" anti tank rifle that was a riot to shoot. A trigger in the right-hand grip controls fire. However, it was the original SS gun which was widely adopted as anti-aircraft gun, being especially widely used by The M829A1 round weighs 20.9 kg (46 lb) and has an overall length of 984 mm (38.7 in). The Japanese Navy similarly used their copy of the FF, designated the Type 99 Mark One cannon on a number of types including the Mitsubishi A6M Zero. By the time of the Winter War - the Soviet invasion of Finland - anti-tank weaponry for the Finns was in desperately short supply with only a few 20mm and some 13.2mm weapons in circulation. Nevertheless, compared to guns with a locking mechanism a fairly heavy bolt must be employed; while to give this heavy bolt sufficient forward speed, a large spring is required (and Oerlikons, distinctively, have this component wrapped around their barrels.) The Lahti L-39 is a Finnish 20 mm anti-tank rifle used during the Second World War.It had excellent accuracy, penetration and range, but its size made transportation difficult. Evaluation would soon enough reveal the 20mm cartridge to be the way of things. The penetrator diameter was also increased from 22 mm (0.87 in) to 25 mm (0.98 in), improving penetrator strength by 67%. The purpose of this development was to improve the performance of the gun as an anti-tank and anti-aircraft weapon, which required a higher muzzle velocity. Very unusually for a high-powered autocannon, the Oerlikon and its derivatives feature blowback operation: the bolt is not locked to the breech of the gun at the moment of firing. An alternative developed during World War II was the so-called fluted chamber, which had grooves that allowed propellant gas to seep between the chamber wall and the case, taking over the role of the grease.[4].

The M829 is an American armor-piercing, fin-stabilized, discarding sabot (APFSDS) tank round. Synergistically with this, a second advantage of this unusual arrangement is that after firing the bolt and case have a short, but significant, distance to travel rearwards before the bolt-end re-emerges and the case in turn begins to leave the chamber; and this in combination with the deceleration provides sufficient time for gas pressure to drop to the necessary safe level. 25mm Hotchkiss penetration performance at 30degrees elevation, 100m - 30mm, 500mm - 29mm, 1000m - 20mm The rimmed 25mm Hotchkiss case was used in the light anti-tank Mle 1934 and AFV gun in French service in the late 1930s, (the anti aircraft 25mm Hotchkiss gun had a shorter case 163mm and is rimless, the AA version does not have the same VSB). The Oerlikon 20 mm cannon is a series of autocannons, based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. The Oerlikon version of the gun was made out of 250 parts: the Polsten was only constructed out of 119 parts. This was on the high end of armor penetration for anti-tank rifles, and the m/42 was able to do this with a weapon weighing just 11.7kg (25 lb) – less than a quarter of a comparable 20mm conventional rifle. According to Jane's, the M829 is capable of penetrating 481 mm (18.9 in) of RHA steel armor at up to a 2,000 m (2,200 yd) range. The M829A3 round has a total mass of 22.3 kg (49 lb) and length of 892 mm (35.1 in). The Oerlikon FF was installed as armament on some fighters of the 1930s, such as the Polish PZL P.24G. It uses 8.1 kg (18 lb) of RPD-380 stick propellant, accelerating a 10 kg (22 lb) depleted-uranium rod penetrator, which can be estimated from cutaway mock-ups to be 800 mm (31 in) long, to a muzzle velocity of 1,555 m/s (5,100 ft/s). The round is specifically modeled for the 120 mm M256 main gun on the Abrams M1A1 and M1A2 main battle tanks. Rated 0 out of 5 $ 150.00 Add to cart. Maximum effective range is 3,000 m (3,300 yd). The 15-round box magazine used by earlier versions of the gun was replaced by drum magazine holding 15 or 30 rounds. It provided a useful increase in firepower over the .50 cal machine gun when adapted and fitted to some aircraft. Some deactivated (a steel bar welded into the … In a typical single-barrel naval version, it is free-swinging on a fixed pedestal mounting with a flat armored shield affording some protection for the crew. This beautiful Finnish made, semi-automatic, war proven 20MM uses 10 round inverted box magazines and weighs a moderate 109 pounds. The gunner is attached to the weapon by a waist-belt and shoulder supports. However, due to delays and then later the Fall of France in June 1940, only 109 guns reached the United Kingdom. Buyer responsible for paying for all shipping and transfer costs. Because the Treaty of Versailles banned further production of such weapons in Germany, the patents and design works were transferred in 1919 to the Swiss firm SEMAG (Seebach Maschinenbau Aktien Gesellschaft) based near Zürich. No locking is required, as with such low-power cartridges the static inertia of the bolt or bolt and slide - the physical tendency of heavy components to resist rapid acceleration - is adequate to ensure that the projectile has left the muzzle and the gas pressure in the barrel is down to a safe level before the breech opens (while the bolt spring also resists the opening of the breech, in practical terms its contribution is too small to be relevant). Squadrons in the Far East were equipped exclusively with Oerlikons. [7] In contrast, 20mm cartridges are far too powerful, and efficient autocannon barrels too long, for this basic system to be practical; so the Oerlikon uses Advanced Primer Ignition (API) to augment the resistance of the bolt. The Oerlikon gun was installed aboard United States Navy ships from 1942, replacing the M2 Browning machine gun, which lacked range and firepower, and largely superseding the 1.1"/75 caliber gun, which was heavier and had less mechanical reliability. * The 20mm was made famous by Bofors-Oerlikon like platforms. 20MM 20mm Vulcan Electric primed, brass case API ammo, loose, Price Each. The next generation ammunition, called 120 mm APFSDS-T M829A2, entered service in 1994, and is the current armor penetrator ammunition being produced by the General Dynamics Ordnance and Tactical Systems for the 120 mm M256 gun of tanks M1A1 and M1A2. When Germany invaded Poland in 1939 the Polsten design team managed to escape to England. It was largely superseded by the Bofors 40 mm gun and the 3"/50 Mark 22 gun. 20mm with suppressor at 2007 Shot Show: 20mm Mag-fed shown in take-down configuration: From left to right:.223, .338 lapua, 50BMG, 20MM Vulcan It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II, and many versions are still in use today.[2][3]. Projectile length: 780 mm; weight: 9 kg. Despite its weight and size, it was appreciated by the troops that used it. To ease the motion of the case, the ammunition needed to be greased, which was a drawback of the Oerlikon cannon. [2] Although the M829A3 fired from the 44-caliber M256 gun has a lower muzzle velocity than 120 mm shells fired from the Rheinmetall 55-caliber gun barrel or Russian 2A46 125 mm gun ammunition, it uses a larger penetrator with increased mass to increase imparted kinetic energy. It became famous in the naval anti-aircraft role, providing an effective defense at short ranges (in practice up to 1.5 km) at which heavier guns had difficulty tracking a target. In 1927 the Oerlikon Swas added to the existing product line. In 1930 Oerlikon reconsidered the application of its gun in aircraft and introduced the AF and AL, designed to be used in flexible mounts, i.e. Lahti set forth to design both a 13.2mm anti-tank machine gun and a 20mm anti-tank rifle. The gun went into service in 1944, and was used well into the 1950s, among other uses, on Cromwell tanks[citation needed] and early model Centurion tanks. The Solothurn S-18/100 20 mm anti-tank cannon was a German and Swiss anti-tank rifle used during the Second World War.It had a semi-automatic action in a bullpup configuration. During World War I, the German industrialist Reinhold Becker developed a 20 mm caliber cannon, known now as the 20 mm Becker using the Advanced Primer Ignition blowback (API blowback) method of operation. Left to Right: Boys .55cal w/5-round stripper clip & ammo pouch Solothurn 20mm x 105B, AP-HE-T (Hungarian) Browning .50cal w/ metal link belt It can also be used against enemy troops and weapon emplacements in trenches, field shelters or in brick-wall […] 40/73 mm Round RHEAT-7MA with anti-tank Grenade GHEAT-7MA (Improved, modernized version of Anti-tank Rounds for RPG-7V) The 40/73 mm Round RHEAT-7MA with Anti-tank Grenade GHEAT-7MA is designed for destroying tanks and self-propelled guns and other armoured vehicles. Developed by the famous Finnish designer Aimo Lahti in 1939, this over-sized rifle soon earned the nickname the “Elephant Gun”. A handful of corvettes were fitted with the weapon toward the end of the war, but it appeared more commonly on frigates and destroyers at the time. This, plus the use of new composites for the sabot, which, together with a new propellant, provide superior penetrator performance. The Royal Navy managed to smuggle out the necessary drawings and documents from Zürich. The 1930s were a period of global re-armament, and a number of foreign firms took licenses for the Oerlikon family of aircraft cannon. [8][9] It was also placed experimentally on the battleships Arkansas, Colorado, Maryland, West Virginia, Washington, Massachusetts, and training ship Wyoming. It is still in use today on some naval units, theoretically as a last-recourse anti-air weapon, but mainly used for firing warning shots or incapacitating small vessels. It saw service in both the Axis and Allied forces and was deployed in many theatres of operations through the war. [4] It costs around $8,500. For this reason, some mountings existed with a height-adjustment feature to compensate for different sized gunners. [6][1] It completed type classification standard in March 2003. The corresponding training round is the M865 costing $1,121. The M829A3 uses a more efficient propellant, RPD-380, boosting its muzzle velocity.

The French firm of Hispano-Suiza was a manufacturer of aircraft engines, and it marketed the moteur-canon combination of its 12X and 12Y engines with a H.S.7 or H.S.9 cannon installed between the cylinder banks. It has a total weight of 41.1 lb (18.6 kg) and utilizes a 627 mm (24.7 in) DU penetrator with a 27 mm (1.1 in) rod diameter,[2] which will reach a muzzle velocity of 1,670 meters per second (5,500 ft/s) using of 8.1 kg (18 lb) of JA-2 propellant. A "piece chief" designates targets and the feeder changes exhausted magazines. In 1924 SEMAG failed. Designated with FF for Flügelfest meaning "wing-mounted", these weapons were again available in the three sizes, with designations FF, FFL and FFS. This is a unfired British Kynoch made Masden 20x120 ball round for the Masden 20mm automatic cannon developed in Denmark in the 1920s for the 20mm Madsen automatic cannon, offered in various mountings for aircraft, AA and anti-tank use, although only successful in the … [2] From patents submitted by Orbital ATK, the penetrator is composed of two sections, an approximately 100-millimeter-long (3.9 in) steel tip and the rest composed of depleted uranium. [2], The M829A1 (nicknamed the "Silver Bullet" by Operation Desert Storm tank crews) proved itself in 1991 against Iraqi T-55 and T-72 tanks during Operation Desert Storm. Check out my other militaria videos. The sabot is of composite material. The Oerlikon firm, named after the Zürich suburb of Oerlikon where it was based, then acquired all rights to the weapon, plus the manufacturing equipment and the employees of SEMAG. Romania purchased 45 pieces from Germany during the first half of World War II.[6]. [10] Its propellant maintains consistent muzzle velocities across operational temperatures from −25 to 145 °F (−32 to 63 °C). The FFL of 30 kg fired a projectile at a muzzle velocity of 675 m/s with a rate of fire of 500 rpm. An improved version known as the 1S followed in 1930. In spring 1941 the Solothurn was tested against the .90-cal. [9], The M829A4 is a fifth-generation APFSDS-T cartridge consisting of depleted-uranium penetrator with a three-petal composite sabot; the penetrator includes a low-drag fin with a tracer, and a windshield and tip assembly. Out of stock. SKU: 00020-004. 20mm Lahti Anti-Tank rifle Archived. In API blowback weapons, the firing pin fires the cartridge while the bolt is still traveling forward so that the gas pressure has to overcome the forward momentum of the bolt as well, before it can push it to the rear. Belt-fed versions of the gun were developed to overcome this limitation. The initial order for 2,501 M829A4 rounds in 2014 had a unit cost of $10,100 each. Very little is publicly known about the round, perhaps due to export restrictions (see International Traffic in Arms Regulations (ITAR)). The new ammunition's performance gains, while classified, result from several new features. The 684-millimeter-long (26.9 in) penetrator together with its sabot weighs 9 kg (20 lb). manually aimed by a gunner. Today the rifles, especially those in working condition, are quite rare and highly sought after. Such armament was installed on the Morane-Saulnier M.S.406 and some other types. Of course that was a lot more money in 1964 than it is now. The FF weighed 24 kg and achieved a muzzle velocity of 550 to 600 m/s with a rate of fire of 520 rpm. It was used on a limited scale as an aircraft gun on Luftstreitkräfte warplanes, and an anti-aircraft gun towards the end of that war. The US Navy operated a quad mount developed for PT boats by Elco Naval Division, Electric Boat Company, called the Elco "Thunderbolt" Mount. Ammunition feed is typically by a 60-round drum magazine on the top of the gun. The Polsten 20mm automatic loading cannon was a low cost development of the Swiss made 20mm Oerlikon auto-cannon, that was simpler and much cheaper to build than the original without reducing its effectiveness. The 20mm is probably the most versatile round ever used while generally being the smallest/entry level diameter of any weapon deemed “cannon” for past century. This variant is unofficially referred to by Abrams tank crews as the "super sabot". Finnish built Lahti Anti Tank Rifle. Apart from changes to the design of the guns for wing-mounting and remote control, larger drums were introduced as it would not be possible to exchange magazines in flight. 20MM 20mm Vulcan Electric Primed, brass case AP ammo, linked in original 28 round can. The Oerlikon was also used as the basis for the Polsten gun, designed by Polish engineers in exile in the United Kingdom. It was not until the Commander-in-Chief of the Home Fleet, Admiral Sir Roger Backhouse, was appointed First Sea Lord that Mountbatten's efforts bore fruit. It is carried in the gun tube by a three-piece aluminum sabot, which separates into three "petals" soon after the round leaves the gun tube. The shell is designed as a conical cavity with a copper lining, behind which is placed an explosive charge. The Lahti L-39 is a Finnish 20mm anti-tank rifle used during World War II. The cannon is aimed and fired by a gunner using, in its simplest form, a ring-and-bead sight. Combined, these features increase the muzzle velocity of the M829A2 approximately 100 m/s greater than the M829A1 (up to approximately 1,675 m/s), while operating at slightly lower pressure. Armor-piercing ammunition (armour-piercing ammunition in Commonwealth English; AP for short) is a type of projectile designed to penetrate either body armor or vehicle armor.. From the 1860s to 1950s, a major application of armor-piercing projectiles was to defeat the thick armor carried on many warships and cause damage to the lightly-armored interior. The penetrator is carried by a sabot during its acceleration in the gun barrel. Source: Sa Kuva All through 1937-1938 Lord Louis Mountbatten, then a Captain in the Royal Navy, waged a lone campaign within the Royal Navy to set up an unprejudiced trial for the Oerlikon 20 mm gun, but it was all in vain. Initially the Oerlikon was not looked upon favorably by the Royal Navy as a short-range anti-aircraft gun. Locally produced derivatives of the Oerlikon cannon were used much more extensively, on aircraft, on ships and on land. This is an inert example of a 30 mm anti aircraft/ anti tank round. 7191 RARE WW2 GERMAN 28/20mm SQUEEZEBORE ANTI-TANK CARTIRDGE - 28 x 188mm Rimmed with headstamp 2h, avu (maker- Silva Metallwerke GmbH, Werk Genthin), 43 (date), [waffenamt], 2.8 cm Patrh PzB” These were fired in the innovative 2.8 cm schwere Panzerbüchse 41 (sPzB 41) or "Panzerbüchse 41" was a German anti-tank weapon working on the squeeze bore “Gerlich” principle. [5] On 20 July 2015, Orbital ATK announced that the M829E4 had passed First Article Acceptance Testing and was entering production. As a result when firing occurs, the forward force of the bolt and spring acts against the force of the propellant gases until the latter overcome the former and start pushing case, bolt and spring backwards. Motor Torpedo Boat Squadron Twenty-Nine Memo to CNO. I placed a Pepsi can beside the mag in the last picture so you can see the size of the magazine. Just a few weeks before the Fall of France, the Oerlikon factory approved manufacture of their gun in the United Kingdom, under licence. Oerlikon realized further improvements in rate of fire on the 1SS of 1942, and the 2SS of 1945 which achieved 650 rpm. In the air, the Ikaria MG FF was used as armament on a number of German aircraft, of which the most famous is the Messerschmitt Bf 109. The gun was eventually abandoned as a major anti-air weapon due to its lack of stopping power against heavy aircraft and against Japanese kamikaze attacks during the Pacific War. This ... and ammo was $2.50 per round. In France, Hispano-Suiza manufactured development of the FFS as the Hispano-Suiza HS.7 and This system permits blowback to be used in far more powerful weapons than normal. Revisa las traducciones de 'anti-tank round' en Español. Price per 28 round can. During the first half of 1939 a contract for 1,500 guns was placed in Switzerland. The first guns were delivered to the Royal Navy in March or April, 1941. Developed as a tank buster, it first saw combat during the Winter War of 1940. This was a Bofors development for their m/40 AA and anti-tank gun. In Germany, Ikaria further developed the FF gun as the MG FF, firing 20x80RB ammunition. 20x145R. Introduced in 1939 and rushed into service for the Winter War, the Lahti L-39 fires a 20mm anti-tank round from a top-loaded magazine, and was capable of successfully engaging the Soviet armor of the era. The Oerlikon 20 mm cannon is a series of autocannons, based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. Lahti 20MM [kygunco.com] Have you been searching for the perfect first anti-tank?Look no further than the Lahti L-39. The new Advanced Combustible Cartridge Case is similar to previous models but has a relocated skive joint placement for better crew-member safety during handling. Similar German installations of the MG FF were not successful. The straight sides allows the case to slide back and forward in the cylindrical chamber. All Oerlikon guns imported from Switzerland, in 1940, were mounted on various gun carriages to serve as light AA-guns on land. It is ironic that forward thinking anti-tank rifle development produced a variety of finely engineered weapons optimized for an outmoded form of warfare. During sustained firing, the magazine must be frequently changed, reducing the effective rate of fire. Prototypes were built and tested in late 1942 and operationally deployed on several Elco PT Boats in the Mediterranean. If the bolt had stopped at the mouth of the chamber as in a simple blowback gun, this momentum would have been neutralized; instead thanks to the continuous movement the momentum acts to counter the propellant gases and slow the rearward travel of cartridge and bolt. This fired a still larger cartridge (20x110RB) to achieve a muzzle velocity of 830 m/s (versus 490 m/s for the original Becker 20x70RB gun), at the cost of increased weight and a reduced rate of fire (280 rpm). The Royal Canadian Navy popularized the use of the Oerlikon gun as an anti-ship and anti-submarine gun - while it was not effective against the armour of most larger ships, it was used extensively and effectively against U-Boats, and on the decks of larger ships. The M829A3 is a further improvement, designed to defeat any future armor protection methods like 'Kaktus' ERA, which was seen on the now cancelled prototype tank, the T-80UM2 "Chiorny Oriol" (Black Eagle) tank. The gun fired through the hollow propeller hub, this being elevated above the crankcase by the design of the gearing. An S 18-154. Hispano-Suiza HS.9, for installation between the cylinder banks of its V-12 engines. 20mm semi auto , Model 39-44 , Comes with the original skies ,barrel shroud , muzzle brake with cover also shoulder rest. The Solothurn S 18-1000 was a Swiss-built 20 mm Anti-Tank rifle which was an upgraded version of the earlier S 18-100. the 20MM Anti-Tank Rifle, Chambered in 20x102mm 'Cannon' Round, absolutely monstrously powerful single shot sniper rifle with intense recoil and a nice bi-pod to stabilize shots, one shot is all you will ever need, hope you enjoy! Unfired, British, 1951 Dated Kynoch made Masden 20x120 Ball Round. Allied navies during World War II. The mass of the penetrator alone is 4.6 kg (10 lb). The M829 is an American armor-piercing, fin-stabilized, discarding sabot tank round.Modeling was designed at the Ballistic Research Laboratory (BRL) at Aberdeen Proving Ground (APG), which was incorporated into the Army Research Laboratory (ARL) in 1992. The Lahti L-39 is a wonderfully interesting 20mm Anti-Tank Rifle (ATR).
