The ejection port cover is one of those small parts most folks never think about until it rattles loose or snaps off mid-range trip. Timber Creek Outdoors built this billet dust cover to be the upgrade you install once and forget about. It's CNC machined from aircraft-grade aluminum and finished with a Type III hardcoat anodize, so it holds up to the kind of dust, mud, and weather your AR-10 sees in the field.
Most stock covers are stamped steel that does the job and not much else. This billet aluminum version trims a little weight off your upper while giving you a cleaner, more finished look on the ejection port. The black anodized finish is corrosion resistant and pairs with just about any build, whether you're running a blacked-out rig or want a subtle base to build a color scheme around. It drops in as a direct replacement for any Mil-Spec ejection port, so it plays nice with standard AR-10 pattern uppers.
This is a straightforward swap for anyone who has done basic AR work before. The cover comes with the mounting hardware you need to get it on the rifle. Depending on your setup, you may need to pull the handguard to get clear access to the port and slide the rod through. Keep in mind AR-10 dust covers aren't always interchangeable with AR-15 parts, so this one is sized specifically for the larger .308 pattern port. A few minutes with a punch and you're back in business.
A dust cover's whole job is protecting the internals of your upper from whatever the day throws at it. Sand at the range, rain on a hunt, or just the grit that finds its way into everything, this cover keeps the action sealed up when the rifle's closed. It's a low-cost, high-value upgrade that makes an older rifle feel dialed in and a new build feel complete.
It's designed to fit any Mil-Spec AR-10 ejection port, which covers the vast majority of .308 pattern uppers. AR-10 covers aren't always interchangeable with AR-15 parts, so this one is sized specifically for the larger port. If you're unsure about your particular upper, measure your ejection port or check your receiver pattern before ordering.
Yes, it includes the mounting hardware you need to get it on the rifle. Most builders can knock the install out with a basic punch and a few minutes of time. Depending on your handguard, you may need to remove it first to get clear access to the port.
It's CNC machined from aircraft-grade billet aluminum and finished with a Type III hardcoat anodize. That combination gives you a lightweight part that resists corrosion and holds up well to dust, moisture, and hard use. It's a step up in both looks and longevity over a standard stamped cover.
Not at all. Swapping an ejection port cover is one of the more beginner-friendly jobs on the AR platform. As long as you're comfortable using a punch and possibly pulling your handguard for access, you'll have this on in short order.
