This barrel is 2 months old with approx. 900 rounds through it. Like new, I swapped it out for a threaded barrel. Excellent barrel for someone still in a ban state. There is no A frame front sight as this barrel was used on a FIRSCH RIS style flee float kit with gas block. The barrel is 416 stainless steel and SS 556 is stamped on the barrel. Also this barrel was Blacktac treated and has a 1 x 9 twist.
I just paid $156 + shipping for the exact same barrel, except threaded. Letting this one go for $125 SHIPPED via USPS Priority Mail CONUS ONLY. Will except best offers for the next week or so if I do not sell it, no trades please.
Here was the barrel mounted on the rifle:
