Need to revise my earlier review. On closer inspection and finalizing some builds: the castle nut is barely dimpled, and there is something out of spec with the machining – fit is loose with varying gap size to their uppers. Plus the forge lines do not match. This latter is well known in the community, but none of it should be acceptable given LMT’s “status” and premium cost.

Best setup by LMT if your wanting to build a pistol. As always fit and finish are top tier, you get what you pay for. Huge thank you to Rooftop defense for offering this LMT pistol lower receiver setup at a great price and supper fast shipping. My favorite shop to purchase LMT products as well as others.

Precisely what I was looking for to finish my AR pistol build. Always wanted a LMT and it certainly doesn’t disappoint. It’s incredibly smooth in every facet. Coordinating the transfer was easy and the lower was delivered in a couple of days. Will definitely order from Rooftop again. Thank you!

Fit and finish looks excellent. It’ll be a bit before it gets a mate and tested. 5 stars is for the best retailer around. Appreciate the meal and sticker, but most of all the pocket Constitution! What an outstanding idea! Keeping a couple for home and then start handing out. When I run out of options for that, I’ll start donating to the public school teachers. Pretty sure they don’t adhere to page 46.
