The gun was also widely used in the Cold Charlie counter-sniper technique, where the Finns would use a mannequin to pose as an officer sloppily covering himself. Because of this, Finland finally settled on the 20 mm design and started production. Only two 20 mm rifles and a few 13.2 mm machine guns made it to the front, where the 13.2 mm machine guns were found to be ineffective and unreliable while the larger 20 mm rifles proved successful against Soviet armour. To reduce recoil, the rifle is equipped with a five hole muzzle brake and a padded leather recoil pad.ĭuring the Winter War (1939-1940) Finland lacked anti-tank weaponry. The rifle is a semi-automatic, gas operated weapon with the piston located beneath the barrel and ammunition feed from detachable top-mounted magazine with bottom ejection for the spent cartridges. After test firing both weapons in 1939, they found that the 20 mm rifle displayed better penetration. As a result Lahti designed two competing anti-tank weapons: a 13.2 mm machine gun and a 20 mm rifle. Officers who wanted smaller calibre anti-tank weapons believed that the muzzle velocity of 20 mm shells was insufficient to penetrate armour and a weapon with a higher rate of fire and in a smaller calibre would prove useful. Aimo Lahti had doubts about the original idea of a 13 mm anti-tank machine gun and started working on a 20 mm design.
