Description
The Rosco K9 Sauce Pack is a 5.56x45mm NATO barrel assembly for AR-15 platform builds, sold as a bundle for carbine or pistol projects. The barrel is stainless steel with a black nitride finish for corrosion resistance and durability under hard use.
The 12.5 inch barrel uses a 1:7 twist rate to stabilize a range of 5.56 NATO bullet weights. The 1/2x28 thread pattern accepts standard muzzle devices, and the included HUXWRX Flash Hider QD XL is pinned and welded in place. The assembly weighs 27.05 ounces, or about 1.69 pounds per the listed specification.
