Rosco Husky Barrel Features The Rosco Manufacturing Husky Barrel takes on a SOCOM 12.5 profile built to resist the heat buildup and barrel whip that can affect accuracy during rapid or sustained strings of fire. The barrel is machined from chrome moly vanadium steel and button rifled to Rosco s own accuracy standard giving the barrel consistent rifling for repeatable shot placement. A 1 in 7 twist rate stabilizes a broad range of 5.56 NATO bullet weights from lighter varmint loads up to heavier match projectiles. Despite the heavier Husky profile the barrel adds only a few ounces over Rosco s lighter Bloodline 12.5 barrel. The barrel is finished with a chrome lined phosphate coating which protects the chamber and bore from corrosion while also easing cleaning after heavy use. A 1/2x28 thread pattern on the muzzle accepts standard 5.56 compensators flash hiders and suppressors. At 12.5 inches this barrel length suits a pistol length or short barreled rifle build intended for maneuverability without sacrificing much velocity. Builders looking for a SOCOM profile barrel with improved heat management over a standard contour get a durable chrome lined option from Rosco s Husky Series.
