REAL AVID MASTER-FIT® 3-PRONG FLASH HIDER WRENCH

The MASTER-FIT® Armorer’s Crowfoot Wrench series is engineered for the builder who demands shop-level precision and a mar-free finish. When it comes to AR15 assembly, generic, sloppy-fitting wrenches can round off edges or slip under pressure. Each Master-Fit wrench is precision-machined to provide a high-tolerance, no-slip interface with your specific hardware, whether you are clocking a muzzle device, staking a castle nut, or seating a stubborn free-float barrel nut.

PROFESSIONAL PERFORMANCE

Every wrench in this lineup is designed to fit a 1/2-inch drive torque wrench, allowing you to meet exact manufacturer specifications for safety and reliability. Built from high-quality materials, these tools are designed to withstand high-torque demands without flexing or deforming, significantly reducing the risk of "tool walk" or finish damage on your receiver and handguard.

COMPREHENSIVE COMPATIBILITY

The Master-Fit system allows you to select the exact tool required for your specific build. From standard Delta Rings and A2 extension tubes to oversized free-float barrel nuts and specialized 3-prong flash hiders, these individual heads provide a centered load distribution that standard multi-tools cannot match.

FEATURES

• Precision-machined for tight engagement and reduced risk of nut rounding
• Fits all standard 1/2-inch drive torque wrenches
• Supports accurate torque application for critical components
• Minimizes marring and component damage during installation
• Specialized profiles for low-clearance and metric applications

The REAL AVID Master-Fit® Wrench Heads are precision-machined crowfoot wrench attachments designed to work with the Master-Fit Torque Wrench System, providing secure engagement for AR-15 and firearm-specific maintenance tasks. Constructed for durability and precise fitment, these specialized wrench heads help deliver accurate torque application while reducing the risk of slippage, marring, or damage to firearm components during installation and servicing.
