Cyma CM.125 USP Fire Selector Pin/Positioning Grain/Spring Guide

This is a replacement for the Pin that makes the snap mechanism of the fire selelctor switch of the Cyma 125 (USP) possible. It is that thing that flew across your room, nowhere to be found, when you took out the fire selector unit out of your airsoft pistol.

Sometimes, while switching to SEMI-Auto, it still shoots fullauto, but thats propably just the tolerances from printing because it does not snap in as precise as the original part.

****V2 is a bit bigger and increases the spring force significantly. It fixed the full-auto issue on my gun!

// READ THE FOLLOWING CAREFULLY!!!!!!!!!!!!!!!

In order to print this you will need to turn on DRAFT SHIELD in your printing settings! This will force the printer to make a skirt to the height of the part. This is ABSOLUTELY NECESSARY so the part can cool down in between layers.

YOU WILL NOT BE ABLE TO PRINT THIS WITHOUT A DRAFT SHIELD!
