Hello I have a CarbonSix carbon fiber prefit barrel. It’s 22 inches long. 1-8 Twist Muzzle Threaded 5/8 - 24 Chambered for 6.5x47 lapua. Light Sendero contour. Weights 2 lb. 12 ounces with nut. Nut is included. So is a threaded muzzle cap. Less than 100 rounds fired. No issues getting sub moa with the loads I tried. Just shot the 130 Berger’s. Only selling because I have too many irons in the fire. Don’t really see me shooting this in the next few years. Kind of an impulse buy. Lol. Let me know if you have questions SOLD!
