YHM Turbo K-RB Integral Suppressed Upper | 5.56 | YHM-8025

The Yankee Hill Machine (YHM) Turbo K-RB integrally suppressed upper receiver group combines an integral Turbo-style suppressor pinned and welded to an 11.5-inch barrel for a compact, factory-integral suppressed 5.56 solution. The assembly ships with a 10-inch MR7 M-LOK handguard and a flat top A3 upper receiver; it does not include a bolt carrier assembly or charging handle. The integral design reduces overall system length compared with a separate suppressor mounted on a longer barrel.

It is particularly suited to range training where repeated live-fire and reduced report are priorities, and to short-barrel suppressed carbine applications where system length and balance matter.
