Description

A spring-less, zero resistance, high amperage, plug in tailcap upgrade that delivers full power in a 5+ amp setup created by Moddoo.

And enhanced Z41, press for momentary and twist for constant still apply. 

Carved from solid brass, OVEREADY Zero Resistance Z41 mods allow more energy to travel from your battery to your LED or bulbs than any spring equiped clicky or twisty configuration, particularly with loads in excess of 5 amps.

THESE DELIVER OVER 200 EXTRA LUMENS OUT THE FRONT when used with our Direct Drive Triple XPG drop-ins compared to a McClicky

Installation:

  • Pull the spring from your aluminum cup from your Z41
  • Pull the aluminum cup from your Z41
  • Separate out the factory rivet
  • Drop in the brass ZERO RESISTANCE mod
  • Secure it, by tapping the factory rivet into the center
  • Enjoy your light brighter than ever before.

Caution:

  • Test battery fitment carefully the first time that you use this tail mod. Screw cap on slowly to be sure that you do not crush your cells.
  • As this lacks any spring, switch deactivation force now comes from above your battery.  Smooth battery movement inside the flashlight body is vital.
  • This mod should work perfectly on any single cell bored SureFire®, and many other lights.
  • This mod will deliver all of the current to your drop-in that is available.
  • Use care when lighting up your direct drive setups.
