Sons of Liberty Gun Works 14.5″ .223 Wylde Midlength Precision SPR Barrel
The SOLGW Precision barrels are unquestionably the most accurate barrels Sons has ever offered.
Optimized for accuracy, the SPR contour and 5/8×24 threads at the muzzle are by no means lightweight, but they are routinely shooting 1/2MOA groups with multiple types of ammo.
The Precision series is 416R stainless steel, black oxide coated, and cut with .223Wylde chambers. These barrels are also polygonal rifled with a 3 groove, 1:7 twist bore.
Please note that these barrels will have a shorter lifespan than 4150CMV barrels, however their warranty still applies. If you can manage to shoot one out, SOLGW still replace it for you free of charge.

Great barrel and great shipping from Rooftop Defense. I installed this barrel on a custom DMR build that is suppressed with a Sandman X so wanted a shorter non SBR build. It shoots 1 MOA at 100 yards with a variety of different ammo but currently shoots Hornady Black 75 gr .223 the best for the price. Happy to support a great company.
