Just picked up the LMT M4 upper. The tolerances are VERY tight on my MARS lower. There is no movement whatsoever, which is what’s expected from LMT. As always, Rooftop’s shipping was extremely fast. Ordered on a Wednesday, received on Friday. Thanks again Rooftop, I appreciate your great service!

Well built, fit to lower was best I’ve seen of any AR, would expect nothing less from LMT. Service from Rooftop Defense is some of the best. Will answer any questions and even give you honest input on those questions you may have.

The upper is very high quality, there not much you can say about an upper. What’s even better though, is rooftops shipping and customer service. My package shipped the same day. I couldn’t be happier with rooftop defense!
