An early Colt Thompson, (S/N 11xx) came into the shop with a bulged barrel. Gary’s Bunker did an R&R on the barrel with a correct period replacement, timed and cross pinned the type I Cutts compensator. Gary’s Bunker entered into the NFA market back in 1981 with its first model 1928 TSMG. We have dedicated tooling and over 30+ years of experience building and restoring vintage Thompson SMGs.
