Sons of Liberty Gun Works Precision SPR .223 Wylde 18" 1:7 5/8x24 Muzzle Thread Rifle 416R Stainless Barrel 18Precision-SPR-223

The Sons of Liberty Gun Works 18" Precision SPR Barrel is a standalone rifle component engineered for long-range consistency and durability. Machined from 416R stainless steel, this barrel features a heavier SPR profile and 3-groove polygonal rifling to minimize projectile deformation while maximizing velocity. The inclusion of a rifle-length gas system ensures a smoother, softer cycling impulse, which is critical for maintaining a steady sight picture during precision fire. It is finished with a robust black oxide coating and is chambered in .223 Wylde for compatibility with both .223 Remington and 5.56 NATO ammunition.
