M118lr Sbn Barrel .308 Win 16 1-10 Rifle-length Black

The M118LR SBN Barrel .308 Win 16" 1-10 Rifle-length Black from Criterion Barrels Inc is a precision-engineered barrel designed for shooters and operators who demand match-grade accuracy in a compact, lightweight platform. Built on decades of military and law enforcement ballistic science, this barrel delivers the terminal performance characteristics of the M118 Long Range cartridge in a short-barreled configuration ideal for CQB-capable rifles, home defense builds, and tactical precision shooting. The 16-inch length preserves velocity for .308 Winchester loadings while maintaining maneuverability in confined spaces—a proven trade-off used by professional marksmen worldwide.

This barrel features a hybrid contour that balances mass and stiffness, reducing harmonic oscillation for tighter shot groups while keeping total weight at just 2.5 lbs for improved handling and reduced system fatigue during extended shooting sessions. The 1-in-10 twist rate stabilizes 168–175-grain match bullets reliably, the standard for M118LR ammunition and precision .308 loads. Machined from hammer-forged steel and finished in durable black oxide, the barrel resists corrosion in field conditions and maintains finish integrity through repeated cleaning cycles. The 5/8-24 threaded muzzle accepts suppressors, muzzle devices, and precision accessories, providing mounting flexibility for sound signature reduction or recoil management without compromising accuracy potential.

Professional shooters, precision rifle competitors, and tactical professionals will find this barrel compatible with AR .308 (LR308, DPMS) platforms using rifle-length gas systems. Installation requires proper headspacing tools and torque specifications typical of .308 AR builds; end-users should verify bolt and upper receiver compatibility before assembly. The rifle-length gas system length ensures reliable cycling with quality ammunition while minimizing short-stroke recoil impulse compared to carbine-length alternatives. This barrel is ideal for those building a sub-16" legal precision rifle or upgrading an existing .308 AR platform for improved accuracy and durability.
