5.56 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. 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. Both uppers were a dream to shoot. Your builds are impeccable and would certainly recommend them to anyone. Felix

Second Piston Upper Purchase
This is my second upper purchase from B.R.A. within the last 7 months. Like my review on the first purchase of the 7.62x39 Spartan Piston Upper with MI quad rails, I was also very impressed. It's great that they have options to choose from and will help you on your order. Have not shot with this upper yet but I'm sure it will function flawlessly like my first one. I found that lubricating the feed ramp with a little gun oil right before you go the range will reduce any feeding issues even with cheap ammo. Thanks again Teresa and Charles for another great upper.
