YHM 556 marked dust cover
Reviewed on April 18, 2026Verified with Build

Yankee Hill Machine dust cover with the 556 NATO stamp on the cover face is a nice authentic touch on a military style build. Comes complete with rod, spring, and c clip preinstalled. Spring snaps the door open every time the bolt cycles. Easy install.

YHM dust cover simple win
Reviewed on March 21, 2026Verified with Build

Replaced a generic dust cover with this YHM 556 marked one. The caliber stamp is a small thing but I like it. Spring tension is correct, pops open hard when the bolt cycles. Hinge pin and c clip went together easily with the right tools.

YHM dust cover
Reviewed on February 19, 2026Verified with Build

standard 556 size, fit a BCM upper without any fuss. spring tension snaps it open quick when you charge. the YHM stamp is on the inside so it doesnt mess with the receiver aesthetics
