Armorer's Master Wrench™

Professional Grade AR15 Builder's Tool

When it comes to using the Armorer’s Master Wrench™, think precision. The ergonomic handle gives you the ability to apply serious torque needed to remove stubborn, crusted-on barrel or castle nuts without marring your firearm or stripping the nuts. The tool holds shape under pressure and has deep set sockets to grip your nuts and keep them gripped. The torque wrench attachment point allows you to apply accurate and critical torque adjustments to the barrel nuts, castle nuts, muzzle brakes, flash suppressors, and fixed stock receiver extensions. Plus, this is the only tool in the category to include a fully-functional, customizable armorer’s hammer in the same tool.

Hardened stainless steel for maximum strength and durability.

The steel in the Armorer’s Master Wrench™ is hardened to twice as hard as its nearest competitor. This means that when you have a stubborn nut, you can be confident that you have the right tool.

Three interchangeable hammer heads (nylon, rubber, brass).

There is no need to go searching for a hammer when a pin needs to be tapped. The Armorer’s Master Wrench™ has three interchangeable hammer heads that are stored on the side of the tool and has one fixed steel hammer head.

Ergonomic design lets you torque all day.

Whether you are battling a flash suppressor that has become nearly welded to your rifle from high-temp heating/cooling cycles or making precise adjustments that require care and attention - the ergonomic grip gives you the control you need while providing a handle that is meant to hold.
