The Wheeler Delta Series Crowfoot Wrench is a purpose-built tool for serious AR-15 and AR-10 builders and gunsmiths. This is not a compromise—it's a precision instrument.
Proper barrel nut installation is critical to AR-15 and AR-10 reliability and accuracy. A crowfoot wrench allows you to apply torque directly to the barrel nut while keeping your torque wrench aligned with the receiver—essential for consistent, repeatable results. Wheeler's precision engineering means this tool fits right the first time, every time.
Whether you're building your first AR or maintaining a dozen, this wrench delivers the precision and durability you need. It's the kind of tool that becomes indispensable in any serious shooter's toolkit.
