Czech Sa vz. 26 SMG

The Czech Samopal vz. 26 was one of a family of submachine guns (the vz 23-26) that pioneered the use of bolts telescoped out forward over the barrel,allowing guns to have much better ratios of barrel to reciver lenght than before. The guns actually have quite a few interesting mechanical details, althuogh in my opinion they fail to make it particularly desirable gun for actual shooting.
