The LBE Unlimited AR-15 Ejection Port Cover Spring (LBE Unlimited part no. AREPS20PK) is a black, 302 stainless steel spring that keeps an AR-15’s dust cover shut until the bolt cycles and swings it open, sold as a 20-pack for builders and armorers. LBE Unlimited machines these springs from corrosion-resistant 302 stainless steel and manufactures them in the USA. A weak or broken spring leaves the ejection port door hanging open or rattling loose, letting dirt and moisture into the action between shots. A 20-pack keeps you stocked without a special order for a single small spring.
