    First Off thank you for a speedy delivery, even though it felt like longer than it was. I was really excited about trying this upper, when it arrived it was packaged very well. I inspected the upper quite well before installing on my lower, it for perfect. Inspected rifle and cycled a few times decided I needed a test fire, loaded a pmag with 5.56 and headed out back. It fired flawlessly. I’m very pleased with this purchase. I will be ordering another upper like this but in 7.62.

    I’m really happy with this upper. It looks great, its very well made and you can’t beat the price. I was a little worried about the accuracy with the price being so low but after two trips to the range I’m very pleased. I’m not a great shot by any means and I put 20 rounds in sub 2″ MOA @100yds. My next purchase will be the some upper in 300 AAC Blackout.

    I purchased this upper when it was on sale for a great price. I talked to Christina and had several questions that she awnsered. I am very pleased with the way this upper looks and fits my lower. I am waiting to get the stock and will be ready to go to the range. Also, the shipping time frame was excellent. Arrived sooner than anticipated. Thank you CBC
