Strike Industries Ultimate Dust Cover AR-10 .308 3.46" Black Polymer

The Strike Industries Ultimate Dust Cover is a drop-in replacement ejection port cover designed specifically for the AR-10 .308 platform. Built around a 3.46" footprint, this dust cover delivers a more durable and functional alternative to factory sheet-metal dust covers on standard AR-10 uppers.

Constructed from a high-density polymer, the Ultimate Dust Cover is built to handle hard use without corroding, rusting, or fading over time. The matte black finish blends with most factory and aftermarket upper receivers, and the non-metallic construction keeps weight to a minimum while staying quiet in the field. The cover material is lead-free.

An adjustable detent set screw lets the shooter compensate for wear on the receiver's cover channel and dial in opening tension to taste. A spring-loaded internal detent rod makes installation and removal straightforward, so swapping or servicing the cover can be done at the bench in seconds.

Designed to fit standard AR-10 upper receivers chambered in .308, this Strike Industries dust cover installs in place of the factory part and uses the same hinging and latch geometry as a mil-spec cover, making it a clean, lightweight upgrade for any AR-10 build.
