    Ordered this on a Friday, had it the next Tuesday. Great quality product! Excellent finish and fit, comparable with the high end (high dollar) products I’ve tested. I used this upper for developing my subsonic and standard close range munitions. I recommend CBC to all of my range/hunting friends.

    I bought this upper several months ago. I am very pleased with the fit and finish. It has been accurate and good groupings (when there is a good shooter behind the trigger) and really enjoy shooting this. It is on an Anderson lower. Fits well. At CBC’s suggestion, I went with an H2 buffer…..works well. I used their black nitride BCG…..no failure to feed or return to battery. perfect ejection. I plan to buy CBC again. thanks.
