Sons of Liberty Gun Works, SPR Barrel, 223 Wylde, 1:7 Twist, for AR-15

The Sons of Liberty Gun Works SPR precision barrels, optimized for accuracy, consistently achieve 1/2 MOA groups with various ammo types. Made from 416R stainless steel with a black oxide coating, they feature a .223 Wylde chamber, SPR contour, 5/8×24 muzzle threads, polygonal 3-groove rifling, and a 1:7 twist. While less durable than 4150CMV barrels, rest easy knowing it’s backed by SOLGW’s lifetime warranty (ie. they’ll replace it if you manage to shoot one out).
