M118lr Sbn Barrel .308 Win 18 1-10 Mid-length Black

The Criterion Barrels Inc M118lr Sbn Barrel .308 Win 18" 1-10 Mid-length Black is a precision-engineered rifle barrel designed for law enforcement designated marksman rifles, tactical carbines, and long-range hunting platforms. This 18-inch barrel provides the velocity and accuracy required by professional shooters and serious sport competitors who demand sub-minute-of-angle performance at extended distances.

The M118LR nomenclature references the military M118 Long Range cartridge standard, indicating this barrel's lineage in combat-proven ballistics and accuracy requirements. Criterion's mid-length profile balances rigidity and thermal stability, which are critical for consistent shot placement during rapid-fire sequences. The 1-in-10 twist rate is optimized for .308 Winchester, stabilizing match-grade bullets from 168 to 190 grains across standard and magnum loading pressures.

With a weight of 2.6 pounds, this barrel provides sufficient mass for heat dissipation and harmonic consistency while remaining manageable for tactical configurations where operator control is essential. The finish resists corrosion and wear, making it suitable for field environments where moisture and abrasive conditions are constant threats. This barrel integrates seamlessly into AR-10 pattern builds, M110 SASS variants, and other .308 platforms utilizing standard AR-10 chamber specifications.
