    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.

    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.

    Nice Parts Kit

    Installed as per instructions, went smoothly. Notice light machine marks on the face of the hammer. Should not effect function. Coating on trigger seems on par with other high end triggers. Springs are strong.

    Assembled lower, building upper. Have not used it yet but believe it will work fine.

    Thanks for taking the timeout to share your experience. We're glad you're satisfied with your purchase. - AB

    Trigger upgrade

    Loved how smooth this trigger is as well as the lighter trigger pull. Other parts fit well. Here is a picture of the trigger. Didn’t take long for stuff to get here.

    That looks good! Thanks for taking the timeout to share your experience, Ralph. We're glad you're satisfied with the product. - AB
