The LBE Unlimited AR-15 Selector Detent (LBE Unlimited part no. ARSLDT20PK) is a small, spring-loaded detent that seats behind the safety selector in a mil-spec AR-15 lower receiver, sold as a 20-pack for builders and armorers. LBE Unlimited machines these detents from 12L14 steel with a brass finish and manufactures them in the USA. The detent is what gives the selector its positive click between safe, semi, and (on select-fire lowers) auto positions, so a worn or lost one leaves the selector feeling loose and imprecise. A 20-pack means you have enough spares to build several lowers or keep a shop stocked without a special order.
