      Nice lil parts kit

      This lower parts kit worked very well for me as I choose a different stock and trigger. I didn't want to waste money on parts I didn't need. The kit comes with brief instructions and AT3 had the parts sorted in such a manner to make it all easily identified for proper placement.

      We really appreciate you taking the time out to share your experience with us. We work hard to meet expectations like yours, and we’re happy to hear we hit the mark for you. Cheers! - AB

      Perfect

      It was exactly what I was looking for. Everything fits perfect. Every part is high quality, I highly recommend.

      We try our best to provide products that are cheap in price, but not in quality. Thank you for the feedback, Paul! -- LM
