Real Avid Master-Fit AR15 Crowfoot Wrench Set

Real Avid designed the armorer’s toque wrench kits specifically for building and modifying the AR-15 rifle. It comes specialized for precise fit and manipulation of MIL-SPEC and free-float barrel nuts, muzzle devices and castle nuts. The titanium coated stainless steel constructions maintains tight tolerances. The set provides solid, nut-gripping strength and no slip, according to Real Avid.

“We visit with our gun manufacturing partners quite often and they allow us access to their production floors to see how their firearms are assembled. The level of sophistication and precision in their work-flow and equipment is always impressive,” said Howard Tripp, Chief Innovation Officer. “One of the things we continually notice is that almost every assembly wrench used in production is custom made. The reason being, nobody in the gun tool market makes them. … We saw a great opportunity to bring a new professional level of precision, quality and durability commonly found in other mechanical trades, to the gun industry. That’s Master-Fit.”

Meanwhile, the driver “clicks” every eight degrees. The dual-directional wrench also provides the ability to set torque on reverse threads.
