The M118LR SBN Barrel .308 Win 20 1-11 Rifle-length Black from Criterion Barrels Inc is a precision-engineered solution for AR .308 platform builds that demand accuracy and practical handling. This barrel is specifically designed to support the M118LR cartridge, which is the military's long-range designated marksman round. Its 20-inch length makes it suitable for tactical marksmen, long-range competition shooters, and law enforcement precision teams.

Constructed with Criterion's proven cold-hammer-forged steel, this barrel features a 1-in-11-inch twist rate optimized for heavier .308 Winchester projectiles, typically ranging from 168 to 180 grains. This design ensures stable flight and consistent ballistic performance at extended distances. The hybrid contour profile provides a balance of sufficient mass for recoil management and thermal stability while keeping the overall weight manageable.

The rifle-length gas system guarantees reliable operation with standard .308 AR platforms, and the 5/8-24 muzzle threading accommodates most modern suppressors and muzzle devices. This barrel is ideal for precision rifle builds where accuracy, durability, and practical ergonomics are essential. Its design is particularly beneficial for those engaged in tactical operations or competitive shooting.
