Strike Industries Ultimate dust cover in FDE matches Magpul tan parts. Billet aluminum has more heft than stamped covers. Spring snaps the door open on bolt cycling. Anti-rotation slot prevents door rotation. Drop-in install with included c-clip.
snaps shut crisp from the firing position. FDE anodize on mine matches a magpul FDE stock close enough that i didnt mind. pin and spring included, install is two minutes if you have a roll pin punch
