If you want to get rid of your mil spec dust cover and protect your upper, this is the one to replace it with. It’s one of the easiest parts on a rifle to install because of its design. I’ve replaced all of my metal covers with these. The only drawback is just the visual appeal. It is thick and it shows. Approximately 4mm thick. Could be thinner, but that’s just an aesthetic preference.
Pros:
- value
- Price
- Quality
- Ease of installation
Would recommend: Yes

This worked perfectly on the cheapest upper I own. I think the bad reviews are trying to install it in the closed position, which puts the little spring-loaded tab on incorrectly and doesn’t let it spring open. Put it on in the closed position and it will work flawlessly. Great for when you forgot to put one on before installing your handguard �
Best Used for:
- forgot to put the other one on
Would recommend: Yes

Doesn't get much easier to install this dust cover.
Color is darker then I expected but still a good fit.

Installs simply and securely. Latches shut firmly, pops open when bolt cycles. I'm sold.

Controversial take, will probably only work for your mil-spec style upper and not billet � I had an Aero precision m4E1
Doesn't fit! I also have a ultralight to a tactical upper that had a strike industries polymer went on it but the Magpul doesn't fit,
If you're running other than mil-spec you're probably going to have fitment problems so just research it before you buy it
And to be really blunt I'm pretty sure I could break this just like my strike industries one they're not as durable

Magpul had done it again with this amazing and super easy to install port cover. It takes a matter of seconds compared to the many minutes it takes to install a factory port cover. Definitely going to be buying more of these in the future
Pros:
- easy to install
- Ergonimic
Would recommend: Yes
