Experience peak accuracy in your suppressed AR-15 with the Sons of Liberty Gun Works Combat Grade V2 5.56 Mid-Length 13.9" Barrel. This barrel excels in suppressed configurations thanks to increased chamber support and strategic material distribution for minimized POI shift under accessory weight. It features a shortened gas journal that requires low-profile gas blocks for optimized weight distribution. Crafted from durable 4150CMV steel with a 1:7 twist rate, this cold hammer forged barrel delivers precise performance for 5.56mm NATO rounds. The QPQ finish increases wear resistance, and the deep dimple ensures secure gas block installation.
