Gel Blaster Spring Preload Spacer

A small thing I made just for fun. It is a 5mm spacer that gets placed between the spring and spring guide inside gel blasters to give a slight boost to power.
The length can be increased in the slicer to scale the z axis if you want to. Or could print and stack them. I have designed these for my AWM sniper rifle, so it will fit the M24 also. I also found out that the Bing Feng MP7 also uses a similar guide to which this spacer fits also.

I dont have any FPS results to tell so Id love to see your results.
