Echo Zulu Armorer’s Wrench


Stake your AR’s castle nuts faster, safer, & more consistently with Tango Uniform’s new Echo Zulu Castle Nut System.

This patent pending Armorer’s Wrench is precision machined from 4140 alloy steel, heat treated to over 50 Rc, and finished in black oxide to preserve that hardness. This premium tool features a 1/2-inch square drive socket with the same center-to-center distance as a USGI castle nut wrench, so your favorite torque wrench will apply the proper 38-42 FT# when torquing down castle nuts.

When combined with an Echo Zulu Castle Nut (EZCN-CN1) and a straight-wall spring loaded center punch (EZCN-CP1) this Armorer’s Wrench acts as a precision staking guide, allowing for strong, consistent staking with minimal risk of damaging other components.
