5/15/2010 - Sold Out 

We may do another small run in 2011 if we can get receivers and parts.  Interested customers should call to get on the list.

This machinegun is comprised of an unmodified/transferable Stemple 76/45 receiver tube with pin-on type removable trunion, fire control adapter housing, Stemple-compatible bolt, Stemple-compatible cocking handle, Stemple-compatible buffer assembly, and excellent-condition WW2 M1A1 & 1928 components. The system functions exactly like an original M1A1, with the exception that it is full-auto only. The overall appearance of the STG M1A1 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. The system uses unmodified M1A1 & 1928 barrels, extractors, magazines, forends, grips, lower housings, and buttstocks. These machineguns are fully transferable to individuals.

Cycle Rate: 750 rpm (Full-Auto/Safe only... no semi-auto function)
