SOLGW .223 Wylde / 5.56 NATO PRECISION SPR Contour 18" Barrel - Black Oxide

Push your precision rifle build to the next level with the Sons of Liberty Gun Works (SOLGW) Precision SPR Barrel — a match-grade, gas-gun performance barrel engineered for shooters who demand repeatable sub-MOA accuracy and uncompromising reliability. Built around a true SPR (Special Purpose Rifle) contour and refined through extensive real-world testing, this barrel line represents the most accurate offerings SOLGW has ever produced, routinely delivering 1/2 MOA performance with a wide range of quality ammunition.

Machined from premium 416R stainless steel and chambered in .223 Wylde, the SOLGW Precision barrel is designed to maximize versatility without sacrificing precision. The hybrid chamber safely accommodates both .223 Remington and 5.56 NATO while maintaining match-grade accuracy. Its 3-groove polygonal rifling with a 1:7 twist rate stabilizes a broad spectrum of bullet weights, improves gas efficiency, and reduces point-of-impact shifts across different loads—making it ideal for competitive shooting, duty use, or precision gas-gun builds.
