The Strike Industries Ultimate Dust Cover is a billet aluminum dust cover designed for AR-15, M4 and M16 pattern receivers in .223 Rem/5.56 NATO. It features a quick-detach mechanism to install or remove the cover in under 10 seconds, an adjustable detent set screw to compensate for wear, and a built-in double seal to reduce ingress of debris. The package includes the billet dust cover and a pack of four rubber pads, and the product incorporates patent-pending noise-reduction padding for near-silent activation. Note: this dust cover will not properly fit Aero Precision M4E1 upper receivers and will not properly function with the Lantac E-BCG due to carrier and bolt design.
