  1. keith ostendorf

    This upper is definitely worth the money. I haven’t found any blems yet and it’s very accurate and light at 6 pounds 12 ounces with lower attached meaning the whole rifle. Only problem is I bought the BCG with the upper and the gas key is not staked well at all. shells are ejecting at 1-2 o’clock which could be because it’s not broke in yet. I did run with no problems and locked back on last round. I’d definitely buy another one.

  2. William Gallagher

    I finally got to fire my ar with this upper today. Claims it’s blemished but I could not find anything wrong with it at all. I am very pleased with this upper and will buy another in the near future. Great value for this price. Customer service was great as well. Thank you CBC!!
