The LBE Unlimited AR-15 Hammer/Trigger Pin (LBE Unlimited part no. ARHTPN20K) is a mil-spec pivot pin that retains the hammer and trigger inside a standard AR-15 lower receiver, sold as a 20-pack for builders and armorers who need spares on hand. LBE Unlimited machines these pins from 4140 steel, a common choice for parts that see repeated pivoting under spring tension, and manufactures them in the USA. Whether you’re assembling a new lower or replacing a worn or lost pin on an existing build, this pack keeps you stocked without a special order for a single part. It’s sized to drop into any mil-spec AR-15 lower without fitting.
