Buy Drop In AR 15 Triggers | AR 15 Trigger Kits

We offer a complete line of lower parts for the popular AR-15, a rifle that's been in service since 1958 and is the preferred rifle of civilians, military, and police. Some of the most frequently upgraded parts are the AR15 triggers, and we carry a full line of AR triggers and AR 15 trigger kits that allow you to customize your weapon to fire exactly as you'd like. Mil-spec style triggers are available in a wide variety of configurations, including the ALG Defense Quality enhanced unit with a 6.5-pound pull weight and the ALG Defense Combat trigger, which requires a 6-pound pull that's smoother than that of a stock trigger and delivers a sharper break.
