It's great! - Faxon Firearms 16in Legal, SLIM Perm 3 Port Brake,4.5in PENCIL, 5.56 NATO, Mid-Length, 4150 QPQ Barrel

Super lightweight, my AR came in at 4.85lbs with iron sights with this barrel. My goal was under $800 and under 5lbs, this barrel fit the bill for both. Accuracy is pretty good, but not the greatest with 55grain. Better with the 62grain non-steel core I tried. The muzzle brake version does create quite a bit a flash, but helps with lightweight ARs. I would probably get the flashhider version next time if it were legal to use flashhiders in my area. The only downside is that it took 2 months to get my barrel from date of order. Faxon is a small US business and their barrels are in high demand so it's to be expected. I would definitely buy again, overall very happy with it and it met my expectations.
