Original Item. Only One Available. The Sturmgewehr 57 (Stgw. 57 ) is a selective fire battle rifle designed by Schweizerische Industrie Gesellschaft (now SAN Swiss Arms) of Switzerland. The Stgw. 57 is fed from curved detachable box magazines, made from aluminum and containing 24 rounds weighing 250 g (8.8 oz) empty and 900 g (31.7 oz) fully loaded. Special silver-colored magazines that can contain 6 grenade-launching cartridges (Gw. Treib.-Pat. 44) for use with rifle grenades weigh 230 g (8.1 oz) empty and 325 g (11.5 oz) fully loaded. 

Not Available for Export.

Rocket-boosted rifle grenades can be launched with the use of the aforementioned silver-colored magazine. Grenade-launching cartridges enable the Stgw. 57 to fire Gewehrgranaten 58 rifle grenades which weigh 1.16 to 1.18 kg (2.56 to 2.60 lb) depending on the warhead type. These rifle grenades achieve a muzzle velocity of 35 m/s (115 ft/s) and a maximum range of 125 m (137 yd) without the help of a booster charge or a V7 of 70 m/s (230 ft/s) and a maximum range of 400 m (437 yd) with the help of a booster charge. Rifle grenade variants include:

Gw. HPz. G. 58: Hollow charge for heavy armor (direct-fire only), rated for ca. 280-320mm of penetration in rolled homogenous armor.
Gw. St. G. 58: Anti-personnel fragmentation with impact detonator (direct or indirect-fire).
Gw. Nb. G. 58: Smoke canister for reducing visibility (direct or indirect-fire).
Gw. UG 58: Practice (inert orange rubber), with or without booster charge.
