The LBE Unlimited Disconnector Spring (LBE Unlimited part no. ARDS20PK) is a bronze, 17-7 stainless steel spring that seats behind the disconnector in a mil-spec AR-15 trigger group, sold as a 20-pack for builders and armorers. This small spring is part of what keeps an AR-15’s fire control group cycling correctly in semi-auto, so a weak or broken one can cause reliability issues that are easy to overlook during troubleshooting. LBE Unlimited machines these springs from corrosion-resistant 17-7 stainless steel and manufactures them in the USA. A 20-pack means you have enough spares to build several lowers or keep a shop stocked without a special order.
