Description

CMMG Ejection Port Cover Hinge Pin Features The CMMG AR-15 Ejection Port Cover Hinge Pin allows the ejection port dust cover to pivot smoothly opening automatically when the bolt cycles and staying seated when closed. A damaged or missing hinge pin can leave the cover loose misaligned or unable to close fully exposing the action to dirt and moisture. Replacing it with this correctly sized pin restores the cover to proper factory operation. It is designed to work in tandem with the ejection port cover spring for complete reliable function. This hinge pin fits the universal AR-15 platform and installs during a standard upper receiver service or detailed cleaning session. Keeping spares of small hardware like this on hand prevents an otherwise complete rifle from being sidelined by one missing pin. It is an inexpensive practical part for armorers hobbyist builders and owners who like to keep their own spare parts stock. This is exactly the kind of detail that keeps a well-maintained AR-15 running trouble free.
