ZCI V2 Aluminum Ball Bearing Spring Guide

Purchased to replace stock plastic/non-bearing guide in a King Arms V2 gearbox with the following setup:

M130 Deepfire spring.
SHS 32:1 gearset
SHS high torque piston (metal half tooth)
SHS cutoff lever
SHS selector plate
SHS trigger set
16awg PTFE silver coated wiring
Lonex A2 Titan motor
KA Tapet Plate
Stock KA bearings, anti reversal and springset
Deepfire brass o-ring nozzle
Burst Wizard Elite Kong 2 computer/mosfet
11.1 50cc Lipo

This spring guide made it about 10 shots with the lower receiver assembled before breaking and causing the last tooth of my sector gear to sheer off... :(

I might contact Clandestine to see if this would be viewed as a defect or if I am out of luck.. Not that it really matters.. The gears were significantly more than the guide.. I will be very cautious of all ZCI parts in the future!
