5 of 5 dont hesitate April 3, 2017
Reviewer: Eric from Atlanta, GA United States  
At first I was hesitant to buy, due to the fact there were so little reviews on products, but I suppose everyone starts somewhere. Amazing quality, very good quality in craftsmanship, and quality of materials. I did not want to buy from Palmetto State after hearing so many horror stories of their uppers not working, and on top of that the customer service is horrible. These guys answers all of my questions same day and were nice about it. Made it to my house 2 days after buying online. Cant wait to start my next build with them. Ran about 400 rounds through it today and did not have one fte or ftf.
