TWO-PIECE BARREL FOR LOW-ENERGY TRAINING AMMUNITION

摘要

A conversion kit for a recoil-operating automatic pistol to convert it to direct blow-back operation utilizes a two piece barrel having chamber and muzzle portions that may be threaded together. The chamber portion (8) is first installed on the receiver (18) by insertion through the ejection port (19), and the muzzle-piece (9) is then threaded to the chamber-piece to complete the assembly of the barrel.
