This 16-inch barrel is crafted from 4150 CMV steel, ensuring durability and strength under sustained fire. The button-rifled bore with a 1:10" twist rate stabilizes a broad range of .308 Win bullet weights, from light varmint rounds to heavier hunting or match projectiles. Its pencil contour dramatically reduces front-end weight, improving handling without sacrificing structural integrity.
The barrel is treated inside and out with salt bath nitride, increasing surface hardness, corrosion resistance, and barrel life. It’s threaded with a 5/8x24 pattern, making it compatible with most .30-cal muzzle devices and suppressors. Weighing only 1.78 lbs, it’s one of the lightest .308 AR barrels in its class.
