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.

Great Kit!

Great kit. Good as or better than PSA's, but unlike PSA, AT3's kit is $35 less, free shipping, and includes a parts list with instructions.

The only place to buy it.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase. Cheers!

Love it

The only thing it didn't come with the trigger guard roll pin but it came with a trigger guard I ordered so all is well. Trigger feels great. Works flawlessly

The kit is simple, instructions are clear and parts are marked on a sheet.

Fast shipping great customer service. Can’t say anything bad about this set up so far.

Great Parts Kit

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

Thanks for sharing your feedback, James. We're glad you're satisfied with your purchase. Cheers!

Excellent product

This is my first Ar build and it only took me 1 hour to put the lower parts kit into my receiver. The trigger feels great. I'm giving this kit a 4 star rating simply because I wish the parts were packaged in a way to easily identify which parts went with which springs and so on.

Thanks for sharing your feedback, Reginald. Your comments were all noted. We're glad you liked it.
