Beautiful!Review by
I've built 5 other ar's and even returned another brands LFAR set before I got this Mega set, and I've never seen such a well made receiver set and I've looked at many. This set has beautifully milled edges, a great finish, and the fit is unbelievably tight yet functional. There is virtually no play between the upper and lower receivers and all of the body lines are perfectly matched. The hand guard is surprisingly light and again fits beautifully. The only other sets I've seen come anywhere close to this were Rainiers. I can't say how happy I am with my Mega Maten! Buy with confidence, Rainiers customer service is the best.

Rainier Arms was very easy to work with. When you call and have questions they answer the phone and you speak to a person. The Mega product is phenomenal. I have built with a lot of different product but Mega is one of the finest I have used. (Posted on 1/27/2017)
