Extremely accurate barrel that fit perfectly and has a great finish. Jarvis Inc. customer service is top shelf and I highly recommend this upgraded barrel.

The barrel has great fit and finish, solidly accurate. I have the match weight length with porting. Fits in the match weight from HK parts. Makes my gun look very tacticool lol. Many compliments every time I get it out.
