Brownells AR-15 Ejection Port Cover Spring Chrome Silicon

Brownells Ejection Port Cover Spring Features The Brownells AR-15 Ejection Port Cover Spring is manufactured to precise tolerances that match or exceed OEM specifications ensuring the ejection port dust cover snaps open when the bolt cycles and stays firmly closed when the rifle is at rest. Keeping the cover reliably shut protects the chamber and bolt from dirt sand and moisture that could otherwise cause a malfunction at the worst possible moment. Chrome silicon construction indicated by the CS designation gives this spring added resistance to fatigue over thousands of cycles compared to standard steel springs. A weak or broken factory spring is an easy thing to overlook until the dust cover starts hanging open and this replacement solves that problem directly. Sold individually or in 3-packs this spring is well suited both to owners keeping a small emergency parts stash and to armorers servicing multiple rifles at once. It installs quickly during routine upper receiver maintenance without requiring any special tools. Builders assembling a parts rifle from individual components will also find this an essential easy-to-source part. This spring is a smart low-cost way to keep your AR-15 s ejection port cover functioning reliably for years to come.
