Duty-Ready SPR Profile Barrel with Durable Nitride Finish
With an 18 inch barrel for an optimal velocity-to-length ratio, and a heavy profile for repeatable accuracy and rigidity, this Modern series barrel is perfect for your Special Purpose Rifle. This barrel’s tapered profile means that in spite of the weight, it remains handy and easy to carry, and won’t let you down in the precision department.
This barrel also features an Mk12 Mod H profile, with a longer .750″ profile dimension necessary for proper installation of the OPS Inc. 12th model collar and suppressor for optimum fit and function. It also has a rifle-length gas system, giving you excellent reliability and a soft recoil impulse.
