The NORINCO 7.62 mm Type 64 silenced sub-machine gun is a Chinese-designed and constructed gun which combines a number of features taken from various European weapons. The bolt action is the same as that of the Type 43 sub-machine gun which was copied from the Soviet PPS-43. The trigger mechanism, giving selective fire, may have been taken from the Bren gun, numbers of which fell into Chinese hands during the Korean War, although the Bren mechanism was derived from that of the ZB26 series of light machine guns purchased by pre-war Chinese government forces from the former Czechoslovakia. Description The Type 64 is blowback actuated using the 7.62 × 25 mm (Type 51) pistol cartridge held in a curved magazine under the receiver. The chamber contains three flutes each 0.1 mm wide and 0.075 mm deep, extending from the commencement of the small cone to just beyond the mouth of the chamber: a total length of 10 mm. The suppressor is of the Maxim type. The barrel is 200 mm long and is plain for the first 131 mm after which it is perforated by four rows of holes for a distance of 57 mm, each following the rifling groove and each having nine holes of 3 mm diameter, making 36 holes in all. The tube surrounding the barrel continues forward for a further 165 mm and then there is a muzzle cap. Between the end of the barrel and the cap is a stack of baffles each of which is dished with a central hole of 9 mm diameter; two rods passing down through the baffles keep the stack together and properly lined up. The rods can be rotated and then are free to come out through the baffles, allowing ready disassembly. The suppressor is reasonably effective and also has the virtue of preventing any flash from either muzzle or breech. This unusual sub-machine gun was specifically designed and made as a silenced weapon. In most other cases the silencer is fitted to an existing gun, which at least reduces the cost and manufacturing effort.
