STG 1928 Compensated Barrel

The new STG 1928 barrels are threaded 5/8"-24 for use with a suppressor or this compensator. It really helps keep this gun under control with the high ROF.

In 2003, the original inventor, John Stemple collaborated with BRP Corp to make new and replacement parts for the Stemple 76/45 receivers he manufactured prior to the 1986 cutoff. From this came a series of compatible drop-on parts for the unmodified/transferable Stemple 76/45 receivers known as Stemple Takedown Gun (STG) setups. Since nothing is welded or hand fitted to these receivers, changing setups and replacing parts is fast and easy. These are the most finely built and smooth running sub-machine guns on the transferable market. We build them for performance and durability, stock plenty of high-quality spare parts, and provide excellent service. There is only a limited number of these pre-1986 registered/transferable machine guns remaining, so get one while they last.

The Stemple STG M1A1/1928 is assembled from an original Stemple 76/45 machine gun receiver, newly made Stemple-compatible parts, and several original Thompson components. The Stemple 76/45 machine gun receiver inserts into a long receiver shroud. This holds the receiver in position with lower assembly and aligns the sear opening in the Stemple receiver with the new sear in the original Thompson fire control group. The bolt guide, bolt, barrel, mainspring, buffer, and guide rod assembly is a removable unit inserted through the front of the Stemple receiver. These main wear parts are easily repaired or replaced if necessary.

The overall appearance of the STG M1A1/1928 is like that of an original M1A1, with the exception that the rectangular adapter housing for the Stemple 76/45 receiver tube is 3/16 in. taller and 3/4 in. longer than the original M1A1.
