UTG AR-15 Quick Install Dust Cover .223/5.56 Matte Black Polymer

The UTG AR-15 Quick Install Dust Cover is a drop-in replacement ejection port cover built from heat-resistant polymer in a low-glare matte black finish. Marked for .223/5.56, it keeps dust, debris, and fouling out of the action when the rifle is not in use and gives the upper a clean, factory-style appearance.

A tool-free spring-loaded detent design lets the cover snap straight into the upper receiver's dust cover channel without removing the handguard or pressing out the existing roll pin. The detent holds the cover closed under spring tension and flips open smoothly with the bolt. This quick-install layout makes it an easy swap for builders looking to upgrade the look of their rifle, replace a lost or broken original, or finish out a parts build without a trip to the gunsmith.

The cover is cut to fit most MIL-SPEC and billet AR-15 upper receivers, including standard 5.56/.223 platforms and most custom uppers that retain the factory dust cover track. Compact and lightweight at roughly 3.1" long and only 0.6 oz, it adds no meaningful weight to the rifle, and the matte black polymer resists heat and impact while blending with black anodized or phosphate-finished uppers.

Whether you're finishing out a build, refreshing a range rifle, or replacing a stripped or missing cover, the UTG Quick Install Dust Cover from Leapers delivers a clean factory look with the simplest installation on the market.
