7.62x39 Spartan Piston Upper
First and foremost thank you so much for your attention to details and your utmost customer service. I received the uppers on Wednesday and put together immediately. I took it to the range yesterday. Zeroed the red dots at 25 yards and fix at 50. I must tell you the 7.62 upper is quite accurate in the AR platform. I am extremely pleased with the accuracy of both uppers. I fed both steel and brass thru both without any hiccups. I shot a combine total of 700 rounds between the two uppers. Not much recoil to speak of from the 7.62 Both uppers were a dream to shoot. Your builds are impeccable and would certainly recommend them to anyone. Felix
