AR-15/M4 Pin-less Ejection Port Cover Assembly, Engraved with WHO DARES, WINS on outside and
Qui Audet Adipiscitur on the inside.

Dead on Arms offers this creative solution for the often times frustrating job of installing the ejection port cover assembly. By doing away with the loose pin, spring and c-clip and replacing them with spring-loaded, captured plungers that allow you to simply snap the assembly in place without need of tools. The cover is made from manganese phosphate coated cold rolled steel, the pins are made from 416 stainless steel and the springs are made from 302 stainless steel. This is a drop-in replacement for standard ejection port covers.
