Magpul Enhanced Polymer AR-15 Ejection Port Cover (Dust Cover), FDE

The Enhanced Ejection Port Cover is a drop-in upgrade designed to provide an improved installation process, physical strength, and corrosion resistance over the standard USGI ejection port cover.

Traditional stamped-steel ejection ports are malleable, prone to corrosion, and require tools to install. The Enhanced Ejection Port Cover snaps into place easily without having to remove your hand guard or barrel nut, wind any loose springs, or adjust small e-clips. Constructed of impact-resistant injection molded polymer, it is corrosion resistant and will not bend or deform from impacts.

  • Installs easily in seconds
  • Durable, injection-molded polymer construction
  • Corrosion resistant components
  • Will not bend or deform from impacts

Made in the USA.

    First of all, the customer service is phenomenal with Rooftop Defense, from the name of the company itself to the return address on the envelope, to the free package of Ramen noodles with a hand-written note, to the low prices, to the fast shipping… what’s not to like?!

    As for this product, it won’t work properly on the two uppers that were candidates for this thing (both Aero Precision). I’ve contacted Magpul about it and they’ve gotten back to me so I assume they’ll make it right.

    First of all: Rooftop is fantastic, glad to have supported them after the fire. Second of all: This ejection port cover will not play nice with an M4E1 Upper and I learned this the hard way. It does not open and flip out of the way when it is open. Best to just stick with mil spec unfortunately.

    Excellent product, arrived quickly and is super easy to install. Way easier than any other dust cover out there.

    The part was fine, as I had expected from a Magpul item. The customer service was incredible, will definitely be coming back to Rooftop Defense in the future.

    First off…Rooftop Defense, well done on the packaging, well done! I appreciate the gesture and humor by providing some Ramen Noodles to help off-set the cost of my addiction (firearms). The communication was great and the shipping was fast! Magpul makes great products and this one is no different. It was also easy to install. Well worth the money spent!!
