Odin Bbl 300 Blk 16.1" Med Prof Blk

The Odin Barrel 300 Blackout 16.1" Medium Profile Black is a precision-manufactured rifle barrel built for subsonic and supersonic 300 BLK applications across patrol, training, and precision rifle platforms. Machined from 416R stainless steel and hand-lapped for concentricity, this barrel delivers the bore quality demanded by operators running suppressed fire missions or cross-training on intermediate cartridges.

Construction and threading define operational reliability. The barrel features M4 feed ramps for compatibility with standard AR-platform bolt carriers, an 8-twist button-rifled profile optimized for 110–220 grain projectiles, and 5/8-24 muzzle threading to accept common suppressor mounts and brakes. Black nitride finishing resists corrosion and fouling buildup during extended strings of fire. At 1 pound 10.7 ounces, the medium profile balances reciprocating mass for target transitions while maintaining stiffness for precision work. Gas placement at pistol location supports SBR configurations and short-stroke piston systems.

This barrel suits shooters building subsonic-capable platforms, law enforcement marksmen transitioning weapons systems for specialized duty, or precision rifle competitors exploring the 300 BLK cartridge. The 16.1-inch length provides velocity retention for both supersonic duty rounds and subsonic match ammunition while maintaining handling characteristics in confined spaces. Hand-lapping ensures bore runout control critical to suppressor-equipped accuracy and reduces cleaning intervals in sustained fire scenarios.

300 Blackout barrels occupy a distinct niche: purpose-built for suppressed fire where subsonic performance matters, yet equally capable of handling supersonic loads without compromise. The 16.1-inch length sits between short-barreled rifle and mid-length rifle standards, optimizing ballistics for the cartridge's effective range without excessive blast signature. Odin Works barrels are recognized for hand-finishing quality and consistent headspace control, backed by the precision threading and feed ramp machining that distinguish them from mass-produced alternatives.
