Strike Industries AR 15 Ultimate Dust Cover – .223/5.56
The patent-pending SI UDC enables users to attach and detach the cover in 5 to 10 seconds with ease (the stock dust cover will take more time to remove)! It is constructed of a high-density polymer, making it more durable and functional than the traditional dust covers. The Ultimate Dust Cover features an adjustable detent set screw to compensate for wear on the receiver and increase or decrease opening power (To adjust detent: use a small flathead driver and depress the ball detent and adjust as necessary.). Choose multiple designs to customize your AR!
NEW features of the Strike Industries Ultimate Dust Cover Enhanced Version include the added cut-out window on the rod for easy disassembly. It has been made thinner than the original to be compatible with all AR15 receivers on the market, and at the same time, it makes it even lighter, weighing in at only 0.3oz!
Additionally, the “True Seal” Lip has been slightly modified to provide an even better seal than ever before! The patent-pending UDC-E (Ultimate Dust Cover- Enhanced Version) is the modified version of the original UDC for mil-spec receivers.

Big improvement
The dust cover might not be the most important part of an AR, but this is much nicer then a milspec version. It is super easy to install, looks better, and most of all it does a better job sealing off the port to keep debris out. Highly recommend.
