Strike Industries
The Strike Industries Enhanced Ultimate Dust Cover for LR-308 is a quick-detach ejection port cover built for shooters who want a faster, more durable alternative to factory dust covers. If you're running an AR-10 or other LR-308 platform and tired of fumbling with standard covers during field maintenance or range sessions, this polymer ejection port cover locks on and off in seconds—a meaningful speed gain when you need to access the upper receiver quickly. The Capsule Pattern design fits the aesthetic appeal of customized builds while delivering practical function.
Strike Industries engineered this cover from high-density polymer, making it tougher and more reliable than traditional metal or stamped designs. The adjustable detent set screw lets you fine-tune the opening tension as the receiver wears or if you prefer a different feel—a small flathead screwdriver and a few turns give you control. The Enhanced version trimmed weight to just 0.4 ounces and added a cutout window on the rod, so you can disassemble your bolt carrier group without removing the cover entirely. The refined "True Seal" lip provides a tighter barrier against dust and debris, keeping your chamber cleaner between sessions.
This is the kind of upgrade that feels minor until you actually use it—then you wonder why you didn't make the switch sooner. It's ideal for competition shooters, hunters who break down their rifles in the field, and anyone who runs an LR-308 platform and values speed and durability in their accessories.
