Strike Industries rethought the ejection port cover with this Ultimate Dust Cover Capsule for .308, swapping the old stamped-metal design for high-density polymer that shrugs off the abuse a range gun sees. It handles the same job as a factory cover, keeping dirt, dust, and moisture out of your receiver, but adds a few tricks that make life easier when it's time to work on your rifle.
The headline feature here is the spring-loaded internal detent rod paired with a cut-out window on the rod. That combination lets you pop the cover on or off in roughly five to ten seconds using nothing more than a small screwdriver or the tip of a pen. Compare that to fighting with a stock cover and a set of pliers, and you'll understand why this design has a following among people who build and tinker with their own rifles. The polymer construction won't corrode, rust, deform, or fade, and it shaves weight off the front of your upper compared to the metal it replaces.
Because there's no true mil-spec standard for AR-10 and .308 uppers, this cover includes a built-in adjustable detent set screw. That lets you fine-tune opening tension and compensate for a worn receiver, so the door stays shut when you want it shut and pops open cleanly when you rack the charging handle. Plenty of folks report a clean, snug fit on popular uppers like Aero Precision M5 receivers, while other brands may need a little light sanding or filing to seat perfectly. It's a good idea to back off the detent screw slightly before your first close so it doesn't grip too hard, and a dab of blue threadlocker on the set screw once you've got it dialed keeps your adjustment locked in.
The capsule pattern gives your build a more finished, modern look than the plain factory door, which is a nice bonus if you're matching out a full parts kit. It's a small upgrade that pays off every time you open your action.
It's designed for AR-10 and .308/7.62 NATO receivers, and it fits many popular uppers cleanly, with Aero Precision M5 being a commonly reported good fit. Since there's no unified mil-spec standard across AR-10 uppers, some brands may need a little light sanding or filing to seat perfectly. Check your upper's dimensions if you're unsure, and plan on a small amount of fitting for the more oddball receivers.
This cover uses a spring-loaded internal detent rod plus a cut-out window on the rod, so you can install or remove it in about five to ten seconds with just a small screwdriver or the tip of a pen. There's no need to fight with pliers or a hammer and punch like you would on a traditional stamped cover. That quick take-down is a big reason people like it for builds and maintenance.
The set screw lets you increase or decrease the opening tension of the cover and compensate for wear on your receiver. Use a small flathead to depress the ball detent and adjust it to your preference. Strike Industries recommends a drop of blue threadlocker on the set screw once you've got it dialed so your setting doesn't back out.
The high-density polymer won't rust, corrode, fade, or bend out of shape the way thin stamped metal can, and it's lighter too. It also carries Strike Industries' True Seal internal lip, which seals the ejection port tighter than a traditional cover to keep debris and moisture out. For a range gun or a working rifle, it holds up well to regular use.
