Impact Guns provided amazingly fast service. Processing and delivering my AR57 upper in less than a week. Communication emails were clear and concise. Product arrived on time and well packaged. The product itself I would give a 4 out of 5. Only being marked down for what seems to be a 'bit of a cheesy charging handle wich at some point I may look to replace. Other than that it is a very solid piece that I would highly recomend to others that already have or are getting into the 5.7 platform....
