ALG Lower Parts Kit with Grip and ACT Trigger

The ALG Defense Lower Parts Kit with ACT trigger gives you a quality parts kit with a trigger you'll actually WANT to keep. While the rest of the components are the boringly functional and reliable small parts you'd expect, each manufactured to spec for proper fit, the trigger has been replaced with ALG's Advanced Combat Trigger. Polished and treated with with Nickel Boron for a smooth and crisp single stage break, but with the rugged reliability of the mil-spec trigger it replaces.
