Strike Industries products are designed by shooting experts for the shooting sportsman.

The Strike Industries Enhanced Ultimate Dust Cover is the world's first quick disconnect ejection port cover for the AR-308! Manufactured from high-density Nylon polymer, the UDC will never corrode, rust, fade, or deform. It features an internal True Seal lip to better protect your rifle from the elements. A built-in adjustable detent screw allows you to easily compensate for receiver wear, or increase/decrease opening power.

The spring-loaded internal detent rod provides easy installation and take down, often taking just 5-10 seconds! Features a cut-out window for easy installation or removal, without impacting the True-Seal capabilities!

NOTE: The SI UDC has been tested to fit Mega Arms MATEN, DPMS Oracle, SIG 716, YHM, and S&W upper receivers. While it is easily modified to fit other receivers with light sanding, the UDC is not guaranteed to fit all upper receivers.

does not fit


this is the 2nd one I've bought from this manufacturer. the first AR-15 one didn't fit. I thought the AR-10 might work. It did not. Maybe I can file it?

Don't be stupid


Outstanding dust cover, mostly because I can read and saw the part of the description where it lists known compatible upper brands and says that others will require sanding to make it fit properly. But even if it didn't say that, the AR10 platform is notorious for having fit problems between different brands. To blame any one brand/product for that is absurd and moronic.
<br>So, if you are literate and read the product description you can't go wrong with this cover. I probably wouldn't buy one if I didn't already need a dust cover, but it's still a nice added touch.

fits Aero M5 upper

fits my Aero Precision M5 uppers just fine, no modification needed. snaps right in, has that lip that seals up the port nicely.
