    In 1932, the Swiss company «Werkzeugmaschinenfabrik Oerlikon» was developed large-caliber semi-automatic anti-tank rifle (MFR) to get the index SSG 32 (Schweres Selbtsladen Gewehr 32 - heavy semi-automatic rifle model 1932). This weapon had a certain similarity with automatic air gun Becker, which was developed and applied in the German Air Force during the First World War.

    In MFR

    Recharging

    SSG 32 was carried out under the force of the impact. Gun had a massive spring-loaded bolt and fixed barrel. Shot came when the bolt moves forward.

    barrel of the weapon was equipped with a muzzle brake.

    trigger mechanism allows keeping only a single lamp. Practical rate was 8-10 rounds per minute.

    Food arms ammunition made from detachable box magazines, merged horizontally left. Used magazines for 5 and 10 cartridges.

    Sights consisted of mechanical adjustable open sights and sector type flies.

    weapons are placed on the bipod, secured to the front of the barrel. For additional support and fixing weapons in position under the shoulder rest was mounted flap opener.

    Strong recoil partially offset muzzle brake, bipod assembly and buffer-absorber shoulder emphasis.

    Archery PTR is as follows: Platoon arrows on the right side handle weapons until it clicks, put the gun on the fuse and insert store of ammunition. After removing the safety produced guidance to the target and descent. Shutter begins to move forward, seized cartridge and input motion occurred triggering drummer. At this point, the cartridge is not yet fully got into the chamber. Energy gases slowed shutter and pushed him back.

    disadvantage gun was a high speed braking force, which caused a strong surge of weapons, which affected the accuracy. This shortcoming was partially offset by a modernized version released in 1936.
