YHM Turbo Integrally Suppressed Upper Receiver Group, 5.56mm, 12-Inch Handguard

The Yankee Hill Machine Turbo Integral (brand part no. 7125) is an integrally suppressed upper receiver group built around a 10.5-inch 5.56mm barrel with the Turbo suppressor pinned and welded in place, bringing the combined barrel and suppressor length to just over 16 inches so the assembly requires only a single tax stamp. YHM includes a lightweight M-LOK handguard and a Mil-Spec A3 upper receiver with the kit, though it ships without a bolt carrier group or charging handle. The Turbo Integral favors shooters who want a factory-built, single-stamp suppressed upper rather than assembling a barrel and can separately.
