The YHM Turbo integral suppressed upper is a 5.56mm upper receiver group with a Turbo suppressor pinned and welded to a 10.5-inch barrel, and this version carries a 12-inch MR7 handguard (Yankee Hill Machine part no. YHM-7125). Barrel and suppressor together measure just over 16 inches, so the two stay together as one assembly. YHM pairs it with a Mil-Spec A3 flat-top upper and a specially designed gas block that cuts blowback and cyclic rate. The longer handguard gives more rail for a light, laser or forward grip. Add a bolt carrier, a charging handle and a lower, and the result is a quiet 5.56 carbine built as a matched system.

Frequently Asked Questions

What is not included? YHM does not include a bolt carrier assembly or a charging handle, so plan to supply both along with an AR-15 lower.
