Strike Industries Ultimate Dust Cover – AR-10/.308 Standard Black

The Strike Industries Ultimate Dust Cover replaces your AR-10/.308 rifle's standard ejection port cover with a reinforced design that stays open during cycling and closes automatically when the bolt locks back. This upgrade addresses the common issue of standard dust covers flopping closed during rapid fire, which can create distractions and interfere with brass ejection patterns. The Ultimate Dust Cover provides reliable port protection during storage and transport while staying out of your way during operation.

Machined from 6061-T6 aluminum with a black anodized finish, this dust cover installs using your existing C-clip and hinge pin—no permanent modifications to your receiver required. The enhanced spring tension and updated geometry ensure consistent function across extended firing sessions. Installation is straightforward for anyone comfortable with basic AR maintenance and takes approximately 5 minutes with a punch and hammer.
