Armalite 16" AR10-T barrel (pre-owned)

Pre-owned in good condition. Armalite AR10-T 16" Stainless barrel. 16" triple lapped stainless match barrel with 5/8x25 threads. Includes Vltor stainless low profile gas block (with new screws) and mid length gas tube. I believe this is a 1/11.25 twist barrel. Armalite switched from 1/11.25 to 1/10 at some point, but I believe this barrel with made before the change. Barrel shows wear from use but is in good condition. Original owner can not remember how many rounds might be on the barrel but guessed around 500.
