Auto-Ordnance, maker of the semi-automatic Thompson and other vintage American designs such as the M1 and M1A1 carbines and M1911A1 pistol, has a surprise for you. When was the last time the Tommy gun got a serious update? Well, here’s a clue, Franklin Roosevelt was still president. Auto-Ordnance has produced a concept gun with a new streamlined upper receiver, a 16" barrel with a muzzle brake and a rounded aluminum fore-end—and, yes, it’s M-LOK-compatible. Built on a semi-automatic M1927 lower with an all-new side-cocking upper, this Tactical Tommy gun takes your favorite AR pistol grip and has an M4-style adjustable buttstock. The final design hasn’t entered production, but judging by the response so far, it’s coming. Although it will take the excellent Thompson stick magazine, Auto-Ordnance advises it may take a different drum than the one designed by John Taliaferro Thompson and his crew back in 1919. auto-ordnance.com
