Strike Industries Enhanced Ultimate Dust Cover - Capsule - Black
The Strike Industries Enhanced Ultimate Dust Cover is the world's first quick disconnect ejection port cover for the AR-15! 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! This enhanced version is thinner, allowing greater compatibility with nearly any AR-15 upper receiver, including billet uppers, on the market as well as reducing the weight to a minimal 0.3 oz! The new design also features a cut-out window for easy installation or removal, all without impacting the True-Seal capabilities!

Does what it says and was amazingly fast getting here. Awesome company Primaryarms
Easy to install
Easiest dust cover to install. Fit was good on my Spartan Upper.
Works well. Easy install
Easy to install. Better looking than the stock cover. Over all a good buy. Wold have liked a ODG option as well, but can't complain.
Very attractive and functional Dust Cover

Prefer my original
by Justin C.
Excellent shipping with Primary Arms as always!! Doesn't work quite as well on my Spikes lower. I'm taking 3 stars away cause when I close the dust cover it pops back just a little. I tried adjusting the middle detent but it still doesn't completely close tight for me.
So easy install

Ultimate dust cover
by Wallace Dandridge
Great product and Primary Arms as usual ships fast without any issues! If you haven't installed one of these you don't know what your missing, very easy to maintain and you change to a different color or style 10 times quicker than a standard dust cover! I won't be surprised if the military doesn't soon adopt this item.
Looks and Functions Great
by John E
I decided to try this dust cover for one of my latest builds. I like the facg that it is an all in one package and installs so easy compared to the standard cover and c clamp. It also has that custom look.if they made these in billet it would be evn better but the polymer seems fine.

I have purchased from Primary Arms in the past. Every purchase was delivered within the promised time frame. Items were packaged well. Quality has always be top notch, I have even called to speak to a customer service rep and got a live person who answered all my question to my satisfaction. I will continue to shop PA and would recommend there products to others.
Didn't fit right
I installed this on a spikes upper receiver and there was a huge gap between the cover and receiver. It also would not snap shut very tight. I could tap the receiver on the palm of my and the cover would pop open. It looked great, just wish it fit properly. As usual primary arms was great.
Time will tell
I like these new port doors as they look very nice & can be changed out if needed w/o having to remove the barrel. As for the longevity of the polymer- only time will tell but so far so good!
by Paul Caudill
I picked up this dust cover because it matched my YHM billet upper. It is plastic, but I don't think it's going to be a problem, and it installs very easily!
Looks good nad is very light
by Mark Quimby
I'm running mine on a 300 blackout SBR and it has functioned flawlessly through about 100 rounds. It is very light but I am concerned about long term durability since it is made from polymer. At this price point, however, it is well worth the money- even if it has to be replaced every few years. I LOVE how easy the quick detach comes on and off without having to remove the handguards.
Nothing to it.
by Jacobe Kiser
Installed easy and has worked so far on a 458 SOCOM build.
by Joseph McCarthy

Look good and work great
by Anthony Clark
Looks nice, I don't know if it is really that much better of a product than the old milspec type, but it weighs less and works the same.
