I used this KVP barrel and KVP bolt in a parts built 9mm pistol upper. Using MEAN arms Endomags to feed and eject casings, the build works 100%. The barrel has a really good finish to it and fits a standard M4 upper without problems. The price was great, the shipping was quick, I cannot find anything bad to say about this purchase.
