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 manufactures in the AR 15 industry. These are complete 31 piece kits and are compatible with AR 15 and variant lower receivers.
