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.

Everything went together without a problem.
Bought the kit to help build my girlfriends lower. Came with everything that was listed and everything went into place perfectly. Can’t wait to finish the build with her
Very smooth trigger system. No problems yet.
Very easy and inexpensive lower kit, only thing I wished was updated was the stock
Great product. Installed with ease, real high quality and at a great price. I will buy this again
