Wheeler Delta Series AR-15 Professional Armorer's Wrench - Heavy-Duty Gunsmithing Tool for AR-15 Maintenance and Assembly

The Wheeler Delta Series AR-15 Professional Armorer's Wrench is a dedicated multi-tool for anyone who builds, maintains, or repairs AR-15s. If you're assembling an upper receiver, swapping a barrel nut, installing a muzzle device, or doing routine maintenance on your rifle, this gunsmithing tool consolidates six essential functions into one wrench—eliminating the need to hunt through your toolbox for the right size or adapter.

Built from quality materials designed to handle serious gunsmithing work, the Delta wrench puts torque measurements directly on the handle so you can dial in the correct tension on critical components without constantly referencing a separate guide. That's the kind of detail that separates a tool you reach for from one that sits idle. Whether you're a weekend tinkerer fine-tuning your own rifle or an armorer managing multiple builds, this wrench covers the most common AR-15 assembly and maintenance tasks.

The wrench includes fixed wrenches for castle nuts, receiver work, and muzzle devices, plus a torque-rated receiver wrench and barrel nut wrench—the core tools you actually use on every build. No fluff, no unnecessary adapters. It's straightforward functionality at a solid value for precision rifle work.
