The Husky Series gives the take on a SOCOM 10.3. While this barrel isn’t exactly heavy in weight, only a few ounces more than the Bloodline 10.5″ barrel, the Husky profile helps defeat the heat and reduce barrel whip. This barrel is phosphate coated with a chrome lined chamber and bore. Button rifled for that Rosco accurac.
