The Sons of Liberty Gun Works SPR Precision barrel in .223 Wylde is built for shooters who demand sub-MOA accuracy out of the box. This 16-inch barrel pairs a proven SPR contour with a stout 5/8×24 threaded muzzle, giving you room for suppressors, flash hiders, or whatever muzzle device suits your mission. The 416R stainless steel construction, finished in black oxide, is cut with polygonal rifling to deliver the precision accuracy that SOLGW has engineered into this platform — we're talking routine half-MOA groups across multiple ammunition types.

If you're running a precision-focused AR build for hunting, competition, or dedicated range work, this barrel strips away the lightweight frills in favor of accuracy. The heftier profile soaks up recoil and harmonics better than featherweight contours, and the .223 Wylde chamber gives you flexibility — it'll run standard .223 Remington ammo reliably while also optimizing performance with 5.56 NATO loads. Polygonal rifling provides a tighter gas seal and better bullet engagement than conventional lands and grooves, which translates to cleaner velocities and tighter groups.

SOLGW backs the Precision series with their warranty program. These barrels will experience a shorter service life than their 4150 CMV counterparts due to the stainless steel's material properties, but when it comes time to replace one, SOLGW will cover it — no surprises, no fine print.
