    My go to Lower Receiver, ambi function works great!

  2. Delmer974 (verified owner)

    Not my favorite ambi lower. I enjoy the position of other ambi lowers better but it still works well. Lower pairs up great with an MRP upper but others you may have to do a little filling on it.

  3. cbritt12345 (verified owner)

    One of the best ambidextrous lowers out there, paired with the quality that LMT has. Zero issues, would absolutely buy if you find in stock

    Love the ambi controls, the right side bolt catch is great. Can’t wait to finish putting it together so I can test it out at the range.

    Big Tex got this shipped to my LGS within a week of my purchase, arrived in great condition with no shipping or handling marks. Their customer service has great communication, I was notified as soon as it was shipped out with a tracking number, unlike other companies I’ve dealt with that just have packages show up unannounced.

    Great functionality and fit/finish, but be aware that this will not work with all upper receivers. If you have an upper with a forward assist (most billet ones that I have seen) that is closer to the ejection port then this will not work. It will interfere with the right side bolt catch/release.
