Inside the SOLGW SPR Barrels - What Makes Them GREAT
This video details the design and performance advantages of the Sons of Liberty Gun Works (SOLGW) SPR barrels. Key features include P3 polygonal rifling for enhanced barrel life and accuracy, high-grade 416 stainless steel sourced directly from mills for material integrity, and a conservative gas system designed for flat tracking and shootability. The barrel profile is optimized for consistency with minimal contour changes, and the 5/8" muzzle threads contribute to tighter groups and reduced sensitivity to torque.
