9/12/09: 1928 Pattern Available, M1A1 Pattern SOLD OUT

4/08: A review of the prototype STG M1A1 from 2005 was recently published in the May 2008 Small Arms Review magazine. Since then three things have changed in the design and appearance of this firearm.
1) The bolts in the production design are much heavier than the prototype in order to slow the cyclic-rate to approximately 750 rounds per minute.
2) The receiver housing has a slot cut on the left side to reveal the original manufacturer information on the Stemple 76/45 receiver. The BRP CORP logo is engraved on the right side of the housing.
3) We also have a version that uses original USGI WW2 M1928 finned barrels with compensators and lower housings with detachable stocks.

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.
