All barrels feature crisp CNC markings, precision muzzle crown and a chamber and gas port optimized for reliability. 

5.56 NATO

5.56 NATO was developed in the United States and initially chambered in the M16 rifle. It is the standard cartridge for NATO forces as well as many non-NATO countries. It is derived from, but not identical to, the .223 Remington cartridge. We use a NATO, mil-spec chamber in our barrels that is reliable and safe to fire both 5.56 and .223 Remington rounds. This common and easy-to shoot cartridge is ideal for defense, training and small-medium game hunting.

The Special Purpose Rifle barrel  is based on the special operations Mark 12 Mod X. Lighter than a bull profile, the SPR was designed to be an intermediate sniper / designated marksman rifle. The 18” match grade 1-8 twist barrel offers exceptional accuracy with heavier bullets making it a highly effective long range rifle. The SPR is equally at home as a sniper / designated marksman rifle, on the range or as a long range small game hunting rifle.
