The Best Upgrade To Your AR-15 – Your Key To Faster And More Accurate Shooting!
The AT3 2-Stage Trigger drops into your mil-spec lower for a huge upgrade to your accuracy and speed on the trigger press. With a 4.5 lb total pull weight and a durable Nickel Boron finish, this trigger ensures a smooth pull and crisp break every time you squeeze the trigger. Now available with a flat face for an even more consistent pull.
The two stages of this trigger consist of an initial 2 lb pull that brings you to a “wall”, where the hammer and trigger are set to break for the shot. After that, it’s only a 2.5 lb pull to fire, helping you to make accurate shots with short reset in between.
