Tired of swapping out parts? Build the lower you actually want.

This premium lower parts kit features our AT3 Enhanced Nickel Teflon Trigger, giving you the quality trigger your rifle deserves, and the flexibility to tailor your lower to your preference. Now with the option of a classic curved, or modernized flat faced trigger.

This kit is great for any AR builder who wants quality components without breaking the bank, and pairing the pistol grip and trigger guard of your choice with our Nickel Teflon Trigger Assembly. The trigger has a smooth pull and clean break unlike a standard trigger, which can be gritty and detract from accuracy.
