For the best care for your rifle, use an LMT AR-15 Ejection Port Cover, better known as a "dust cover." Keep debris out of your rifle and always close the port cover when not in use. For less than optimal conditions, this ejection port cover is great for use from dry, dusty conditions to rainy, muddy conditions.

Depending on your rifle lower, the AR-15 ejection port cover will not have a place on a sport upper receiver. These typically do not use an ejection port cover or a forward assist. This ejection port cover is for use on AR-15 platforms only. Machined for a precise fit, when closed, it clicks into place and stays closed until the round in the chamber is fired and brass ejects, or until you pull the charging handle and bolt backward.

Installing an ejection port cover can be tricky to do without ruining the finish on an upper receiver. Be sure to assemble carefully or take it to a gunsmith to assemble for you. LMT manufacturers all of their products in the USA and only use high-quality materials.

For added customization to your rifle build, engrave your ejection port cover on the inside or outside. Keep a spare port cover in your range bag with other parts in case of breakage.
