Very Nice (21/11/2014)

Ultimate might be an overstatement but it is a very nice piece.

Easy to install... just wind the spring with you finger and snap it on... no tools required.

Nice finish... does not have that oily metal look of mil-spec covers.

Black spring... hate shiny objects on my rifle

The big selling point for me however is the retention ball is adjustable... I have a brand new upper that seems was cut a little too much and after trying 3 other covers on it I put this on... at first it was still popping open if you just bumped the receiver...so I took a small flathead and turned the set screw a 1/4 turn and BAM... works like a charm.

I don't have any indication on how it holds up to heat and abuse but I would recommend giving this a try on your next build.

Very nice! Wish I had that idea.... (16/03/2015)

I tried this on a 3 gun rifle build I am currently doing. Needless to say, but install took about 30 seconds. Fit and function is perfect with an Aero upper. Looking at cerakoting a finish on it next, but it really isn't needed. I will be using these on any build I do from now on.

I would love to see more of the designs come out from Brownells, like the flag design and others. May have to try some of their other products too.

Less parts is More (02/06/2015)

Installed on a new 5.56 build. Great not having to keep track of several parts or assemble them. Pops right into place BUT you do have to think a second about the spring orientation as you place into position. There are no included instructions, but 10 seconds of thinking and it becomes obvious.

Works flawlessly. No maintenance needed. Does seal a bit better than a standard.

Fantastic Alternative (16/03/2016)

The Ultimate Dust Cover is a great little accessory for many ARs. Standard covers have quickly-worn finishes, shiny silver springs, and often iffy fits in the receiver, and the tiny washers holding them in place are known to pop off when firing, at least with heavier cartridges. By contrast, the UDC is made from a tough, matte black plastic, sports a black spring, and uses a pair of spring-loaded plungers for mounting, making installation easier and preventing lost pieces. The plastic body minimizes weight and is even molded with a lining that actually seals off the ejection port, minimizing oil evaporation and providing a positive "pop" when closing the cover. The issue that prevents a fifth star is that the primary spring should have been made a little stiffer, or rather, its opposing ends set farther apart. Though easier to install, the looser spring allows the cover to bounce when moving and firing, and at least one of its ends is always sticking out to the potential detriment of a passing bit of hand or shirt. (I tried giving it an extra twist for strength the first time around, which resulted in a snapped spring tip and an order for another UDC.) While not much of a problem, it is the sole element that makes me miss the snappier original. But all things considered, the Ultimate Dust Cover is definitely worthwhile.

Great Alternative (22/07/2016)

I've got these on several guns now and they will definitely go on future builds. They are high quality and easy to install. If you've finished your build and look back at your upper and think to yourself, "Oh dang I forgot the dust cover!" With the UDC you won't need to remove the barrel nut to install one.

Good product, but may require fitting (04/01/2017)

This product looks good, functions well, and is about half the weight of a standard milspec dust cover when compared on my scale. The only reason I gave this 4 stars is because mine would not swing open freely when installed on my Aero Precision forged upper. All it took was for me to shave off a bit of material around the two ends by the pin with a sharp knife, but it had to happen nonetheless. After the very minor fitting, it functions flawlessly.

Won't use any other dust cover again (25/02/2018)

So easy to install it is ridiculous and great quality like all Strike products. Ended up replacing the dust covers on all my AR's.
