Machine gun MG3 (MG1A3)

The MG3 (MG1A3) is an open, fully automatic weapon for sustained firing and firing in bursts. It is a "recoil-operated weapon" in which the recoil forces are used to feed and load the cartridges and to extract and eject the spent cartridge cases.

A blan firing attachment which is screwed onto the muzzle instead of the recoil booster permits the use of blank cartridges for training and exercise purpose.
