Hardened Stainless Steel
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.
The 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.
I bought this armors wrench for an M4 build. Worked great on installing the castle nut. Very stout and strong. This is a heavy duty wrench. Would recommend this if you are building an AR15
