Product DescriptionThe Strike Billet Ultimate Dust Cover is a heavy-duty, machined billet aluminum ejection port cover designed for AR-15, M4, and M16 platforms. Its quick-detach mechanism allows fast installation or removal in under 10 seconds, while an adjustable detent set screw helps compensate for receiver wear and lets you fine-tune opening power. Patent-pending noise-reduction padding helps keep activation nearly silent, making it a refined upgrade for hard-use rifles. Includes the dust cover and four rubber pads.Product HighlightsQuick-detach design enables installation or removal in under 10 seconds without extensive disassemblyAdjustable detent set screw helps compensate for receiver wear and tunes dust cover opening forcePatent-pending noise-reduction padding promotes near-silent activationMachined billet aluminum construction for long-lasting durabilityIncludes dust cover plus four rubber pads for noise reductionSpecsBrand: StrikeManufacturer Part Number: ARBUDC223BKUPC: 708747548372Product Type: Billet ejection port/dust coverPlatform Fit: AR-15 / M4 / M16Material: Aluminum (billet)Color/Finish: BlackIncludes: Dust cover and 4 rubber padsApprox.
