Wheeler Delta Series Mil-Spec Barrel Nut Crowfoot Wrench - Black Steel

The Wheeler Delta Series Mil-Spec Barrel Nut Crowfoot Wrench is a professional-grade gunsmithing tool engineered for installing and removing the barrel nut on AR-15, AR-10, and LR-308 rifles built to Mil-Spec dimensions. The wrench provides the precise fitment required to torque a barrel nut to spec without slipping, rounding the nut, or damaging the receiver.

This Delta Series tool is machined from hardened steel and finished with a wear-resistant black oxide coating for long service life in the shop or armorer bench. The open crowfoot geometry slips over a 1/2" drive torque wrench or the Wheeler XL F.A.T. (Firearm Accurizing Torque) Wrench, allowing controlled torque application in the tight confines around an AR upper receiver where a standard socket will not clear.

Whether you are building a new AR-platform rifle, replacing a barrel, or performing routine maintenance, the Wheeler Mil-Spec Barrel Nut Crowfoot Wrench delivers the correct geometry and material strength to do the job right. It pairs naturally with the rest of the Wheeler Delta Series armorer tool line for a complete AR build setup.
