The NcStar TARW2 Gen 2 Armorer's Barrel Wrench is a multi-function tool kit built for AR-15, M4, and M16 platform maintenance and customization. If you're swapping barrels, upgrading your gas system, or performing routine armorer work on your modern rifle, this single-tool solution consolidates a dozen common tasks into one compact package. The Gen 2 design adds versatility beyond the original, giving you the ability to handle everything from barrel nut work to receiver assembly without hunting down a toolbox full of specialized wrenches.
Built from hardened steel and laser-etched with clear labeling for each tool, the TARW2 weighs just 13 ounces and measures 12.9 inches—compact enough to keep in a range bag or truck without adding real weight. The combo design covers GI-spec barrel nuts with standard spacing, as well as free-float setups and common aftermarket patterns like DD and YHM 1¾-inch nuts. Whether you're torquing a castle nut, removing a flash hider, adjusting an A2 stock, or working on lower receiver takedown pins, the right wrench is integrated into this tool. It even includes a 1911 barrel bushing wrench and a hex socket drive for bits—useful if your gunsmithing reaches beyond the AR platform.
NcStar's patented design (US Pat. # D703502) is purpose-built for the shooter who prefers one reliable multi-tool over scattered drawer full of single-purpose wrenches. Black steel finish resists corrosion during storage and field use. For serious AR builders, gunsmiths, and armorer-level enthusiasts, this is the kind of tool that pays for itself on the first barrel swap.
