Easy To Install & More Rugged Polymer Ejection Port Cover from Magpul

The Enhanced Ejection Port Cover is a more rugged drop-in upgrade that can be installed easily on any AR15/AR10 Mil-Spec upper receiver.  This port cover snaps into place easily without having to remove your handguard, barrel nut, wind any loose springs, or adjust small e-clips.

It is designed to provide an improved installation process, physical strength, and corrosion resistance over the standard USGI ejection port cover.

Impact-resistant Injection-molded Polymer

The Magpul AR-15 Enhanced Ejection Port Cover is constructed of impact-resistant injection-molded polymer making it ideal for daily use.  This ejection port cover is very durable and will not bend or deform from impacts during extreme tactical situations or training.

The Enhanced Ejection Port Cover is a reliable and cost-effective alternative for traditional stamped-steel ejection ports that are malleable, prone to corrosion, and require tools to install.

Features:

  • Durable, injection-molded polymer construction
  • Installs easily in seconds
  • Corrosion-resistant components
  • Will not bend or deform from impacts
  • Direct replacement from USGI ejection port cover

Picky Uppers

I've installed several of these (10+) and Strinke's version on standard forged, generic billet, and a few unique upper receivers. Installation is easy and function is as advertised. This one I purchased to go on an 80 receiver set from Daytona and the cover did not want to snap into the closed position. I swapped it for two other Magpuls and a Strike I had in a box and those didn't close either. Reluctantly, I installed a standard milspec dust cover and that one did snap closed. The detent notch on my receiver seems a little shallow. It's the first time I've encountered this issue.
I ended up accidentally disassembling the detent/spring/retainer on the Magpul cover and found it impossible to reassemble. I flung it into the trash. Again, these port covers are great. It just wasn't meant to be for this one build.

Easy Peasy Replacement

It was far easier to install the Magpul enhanced ejection port cover than it was to remove the original one! In my case, it functions better than the original one in that I don't have to press down on the button to get it closed. S&W M&P Sport II.

It's a well made product but the fit and function were horrible on my aero precision m4e1.
