Proof Research Carbon Fiber barrel
the first thing that impressed me about this barrel was the weight. 2.2lbs. I'm used to shooting something the barrel weighs in excess of 6lbs. After some initial rounds to break it in, (not sure it needs that) I proceeded to start testing and developing a load. The barrel seems to be very accutate no matter what i'm shooting so far. I plan on using this in a gun i built for NRL Hunter. While it isn't my first Proof barrel, it is my first carbon fiber and from shooting it, won't be my last. Also kudoo's to Altus, as always a great compnay to work with. This barrel was shipped out to me the same day i ordered it and arrived 2 days later. Thanks
