Great quality build Review by Wesley
Glad I was lucky enough to find this company online, this upper is nice and good quality, I like the design much more than the competitors, simply because its not rounded. Its sleek and good looking. Fires like a champ. Great customer service as well. (Posted on 8/2/2016)
