AR 15 Lower Parts Kit With 2-Stage Nickel Boron Trigger

Black Rifle Depot‘s AR-15 Lower Parts Kit with the Aero Precision 2-Stage nickel boron trigger is assembled with top-tier quality parts. The 2-stage trigger features a durable nickel boron finish and a 4.5 lb total pull weight, ensuring a smooth pull and crisp break each time you squeeze the trigger. An initial 2 lb pull that essentially brings you to a “wall” where the hammer and trigger are set to break for the shot; then add another 2.5 lb pull to fire. These AR-15 Lower Parts Kits are sourced and used by some of the top manufacturers in the AR-15 industry. These are complete 31-piece kits and are compatible with AR-15 and variant lower receivers.
