The SOLGW PRECISION barrels are unquestionably the most accurate barrels we’ve ever offered. Optimized for accuracy, the SPR contour and 5/8×24 threads at the muzzle are by no means lightweight, but are built with accuracy in mind. The PRECISION series are 416R stainless steel, black oxide coated barrels. These barrels are also polygonal rifled with a 3 groove, 1:7.5 twist bore. Choose from: 12.5″ (carbine gas), 14.5″ (mid gas), 16″ (intermediate gas at 13.65″ long), 18″ (rifle gas) and 20″ (rifle 1″ gas) lengths.
