21700 Mech Stacked Kit – by Overpowered Mod Co


The OverPowered 21700 Full Kit is an all new mech designed to maximize performance from the new 21700 battery. It is lined with Delrin to prevent accidental contact with batteries, has a clutch-style button with 3 contact pins to prevent any hot button.

The safety-oriented silver-plated floating 510 connection offers wide-reaching compatibility and the silver-plated multi-piece firing switch contact provides reliably outstanding conductivity from even the most demanding of coil builds. The OverPowered Mech also has a short responsive throw. It is equipped with silver contacts to increase conductivity and has a reverse threaded rattle adjuster.
