556 nato spiral fluted perfection - Alpha Shooting Sports 16in 5.56x45mm NATO Mid Spiral Fluted Nitride Threaded Barrel

Just put this barrel in a stripped upper receiver and Alpha Shootingsports pitchfork handguard combo and I'm loving it so far. Its summertime and ran it hard already, it performed well. Machining is top notch. I was seeing under 1MOA groups at 100 yds with my reloads and PMC ammo. I expected it would group very well with my match loaded ammo. Great build quality for the money. I recommend this barrel for anyone looking to built a sub MOA rifle.
