$28500RCM acquired a very rare HK SR9 Barrel to reproduce. We improved upon it by making it off a Cold Hammer Forged Barrel, 1:10 Twist. These barrels are top of the line. We stepped it up by including a Recessed Target Crown. Chambered in 7.62 Nato Chamber with 12 Flutes. Nitrided inside and out. Not another barrel out there even comes close to this. Being 19.250 will increase muzzle velocities over 100 ft. per. sec. over a standard 91. The SR9-T has an Industry Standard 5/8-24 Thread along with the Recessed Target Crown for .30 Cal
