Our Match V2 barrel is the culmination of over a year’s worth of development. We took all of the best features of the original Match barrel (the pentagonal flat fluting, the 1:10 twist rate, and the chamber specs) and incorporated many of the popular features of our Vapor barrel including an updated hood design and a deep-cut target crown.

NineX19 Match V2 Barrels have been engineered to satisfy even the most discerning shooters and are ideal for everything from top-level competition use to everyday carry.

Precision machining and rigorous QC ensures that every barrel conforms to the tightest possible tolerances and will perform even under the most grueling conditions. Rifled in a 1:10 twist rate, these barrels are optimized for most common bullet weights and are designed to properly stabilize everything from standard 115gr range ammo up through 147gr for defensive applications and competition.

  1. Deshaun Jenkins

    So I’ve been using this barrel in my USPSA Competition gun. It has thousands of rounds through it with very minimal wear. It’s much more accurate than I could ever be and the machine work is PERFECT! With all that being said you can’t pass up on this especially considering the price is unmatched. I plan on getting these barrels in all of my firearms.

    I have put a thousand rounds or so through this barrel and it still looks new and shoots great. The more I run it the happier I am. One small personal dislike for me is the bullet window (or what ever the notch on the top is called). It just dirties up the optic glass which is annoying. I bought the barrel knowing the notch was there, it would just be nice if there was an option without it. I know a lot of shooters and no one I know uses them to check the chamber. Do not let that deter you, however, the barrel is super high quality and for the price I don’t think you will find a better one anywhere.
