This component seals the ejection port when the rifle is not in use, keeping dust, dirt, and debris out of the upper receiver and protecting the bolt carrier group. Whether you're replacing a damaged cover or building a new upper receiver, this kit includes everything needed for installation.\u003c\/p\u003e\u003cp\u003eMachined from durable steel with a black oxide finish, the cover is designed to withstand repeated opening and closing cycles. Installation requires basic tools and familiarity with AR-15 disassembly—the C-clip and rod must be properly seated to ensure the cover pivots smoothly and stays closed under recoil. All necessary components including the cover, rod, and spring are included.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Ejection Port Cover Assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15, M16, and mil-spec AR platform rifles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In (requires basic disassembly)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Dust cover, hinge rod, spring, C-clip\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CMMG","offers":[{"title":"Default Title","offer_id":47934695768319,"sku":"CMMG55BA6E3","price":9.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1256429.jpg?v=1766476476","url":"https:\/\/doublestackstore.com\/products\/cmmg-ejection-port-cover-kit","provider":"Double Stack Store","version":"1.0","type":"link"}
