AAOK

Replaces the steel ejection port cover. Will not rush or stick, and with its adjustable detent pressure, will not damage the weapon's ejection port or cover detent. Durable, hard-wearing and lightweight polymer construction will never deform. Improves ejection port locking. Adjustable opening power solves the problem of worn ejection ports. Instead of replacing a worn upper receiver, replace the ejection port cover with the IDF-023 and tighten the detent tension. Manufactured in Israel by FAB Defense.
