Echo Zulu Starter Kit Stake your AR’s castle nuts faster & more consistently with Tango Uniform’s new Echo Zulu Castle Nut System. This Starter Kit Includes: one EZ castle nut, a bi-directional staking guide, and a straight-wall staking punch. The patent pending EZ castle nut is made from premium 4140 PH alloy steel and finished in long duration, diamond hard black nitride. It was precision machined on a modern Swiss CNC lathe, to tolerances that meet or exceed the mil-spec TDP, including true class 3 threads. The EZ castle nut features eight co-linear wrench & staking notches, allowing for easier visual alignment, and multiple staking locations with even the largest end plates. The bi-directional staking guide is injection molded from premium glass-filled nylon for enhanced durability. Its small, symmetrical design allows it to index around most QD end plate designs. The included staking punch has a straight-wall design so it won’t tilt inside the bi-directional staking guide. It’s made from 17-4 stainless steel and finished in long duration, diamond hard black nitride. The punch’s 4mm shank is standard for most off-the-shelf spring loaded center punches. The straight-wall staking punch and precision staking guide work in tandem with the unique EZ castle nut design, allowing for strong, consistent staking with minimal risk of damaging other components.
