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.

No complaints here. Fast shipping, good packaging, fit and finish grade A. Great job AT3!
Fit and finish of the lol were nice but oh what a trigger. No creep, no grit, and slick, slick, slick. Gotta try one of the 2 stage ones next. After several purchases of several of your products all I can say is you have earned yourselves a loyal customer. Thank you at3 Tactical you folks rock!
I happened to stumble across AT3 while searching for a LPK for my first AR build. After reading the reviews of this LPK along with the affordable price I couldn't pass it up. I ordered it with the MAGPUL FDE grip and trigger guard on a Friday around 1200 CST and received the parts the following Monday! The assembly was easy, plus the kit came with an illustrated parts list. The trigger assembly has some weight to it and feels sturdy and the nickel teflon finish is a plus! I highly recommend this kit and I will plan to use it with future builds. Great product!
Very smooth Finish and a great fit. I would use this product in any new build
Strong springs easy to put together.
