Questions & Answers 2
-
Will this work with a bushmaster xm-15 with a 16” Government profile Barrel
Joe Fritzinger · Apr 30, 2026AT3 Support Team — Unfortunately, this will not fit a standard 16” Government profile barrel because those typically measure .750" at the gas block and taper elsewhere, while this dissipator requires a consistent .650" outer diameter.
