Strike Industries designed the Ultimate Dust Cover for AR-10 (part no. SI-AR-UDC-E-308-01-BK) as a complete ejection port cover upgrade for the AR-10 platform, replacing a worn or loose factory dust cover with one that stays tight for the life of the rifle. An adjustable detent set screw lets shooters dial in opening tension instead of living with a receiver that has worn loose.
