Simple installation
So I messed up and put the barrel on before putting the ejector port cover on. No big deal other than it's an M4E1 with no through hole at the rear of the port cover. So off came the barrel nut and on went the port cover - didn't even have to remove the tiny C-clip! Forward assist was simple to install, mainly due to the M4E1 upper having a threaded pin instead of a roll pin like most. Fit/finish/function are all plenty good, very satisfied!

Works just Fine
Works fine. No issues

The best of the Mil-Spec UPKs
I've used many different UPKs. This is by far the best. The Dust Cover is Rigid and Robust. The Spring is stiff and keeps the Cover opened with Authority.
5
Perfect fit
Fits the Aero upper like it is supposed to. Couldn't ask for better.

Costs a bit more but does the job
Typical UPK that costs a little more because of the name. Was installed in a Brownells Upper Receiver without any issues. Fit and function were perfect. As with all mil-spec dust covers Ive ever owned, expect it to have multiple annoying scratches.
5
Tidy packaging
Comes in a compact cardboard box (sealed, so nothing falls out) a little bigger than a pack of chewing gum. Nice touch: the easy-to-lose c clip (the smallest part on a mil-spec AR) comes already installed on the hinge! No idea on durability, but everything fit a Brownells upper with no issues. Seems good for the price point

Nice quality parts.
Parts were nicely made and finished. Bought this kit as the pictures showed the forward assist button was secured to the pawl with a roll pin like Colt's I have seen. Have had others that were just pressed together come apart and never really stayed together again. Roll pin does secure things so I'm happy.
