The Yankee Hill Machine Billet Upper Receiver, 5.56x45mm NATO, Black Anodized (brand part no. 110BILLET) is styled to match the stylization of YHM’s Billet lower receiver, which the company finished first. Machined from 7075-T6 aluminum with a hardcoat anodized matte black finish, it features M4-style feed ramps and an interior coated with dry film lube for smoother cycling. The receiver accepts standard upper receiver parts and pairs with mil-spec lower receivers, so it drops into an otherwise standard AR-15 build. This is a stripped receiver only; it requires a dust cover, forward assist, charging handle, barrel, handguard, gas block, muzzle device, gas tube, and bolt carrier group to complete. For AR-15 builders who want their upper’s styling to match a YHM Billet lower, this AR15 upper is the matching half.
