Sons of Liberty Gun Works Precision SPR 6mm MAX 18" 1:7.5 Twist 416R Stainless Barrel

The Sons of Liberty Gun Works 18" Precision SPR Barrel in 6mm MAX is a match-grade component designed for long-range precision and consistent performance. It is machined from 416R stainless steel and features the proprietary P3 polygonal 3-groove rifling, which minimizes projectile deformation and significantly extends the barrel's accurate service life. The SPR profile provides a heavier contour that effectively manages heat soak and barrel harmonics during extended shooting sessions. Utilizing a rifle-length gas system, the barrel offers a softer recoil impulse and smoother cycling, which is essential for maintaining a steady sight picture. It is finished in a durable black oxide and includes a 1:7.5 twist rate optimized for stabilizing high-BC 6mm projectiles.
