Rival Hades Spring (120 FPS)

Regular price $5.00 Sale

The Rival Hades Spring is a custom made spring from a K26 that offers about a 120FPS average compared to the stock average of 90FPS. This mod can be pretty challenging but the results are very worth it! 

You’ll need to take off the whole front plate and grip, nozzle and rotating chamber. You can take the whole internals out but we found it’s a shorter mod if you keep everything in. Next you’ll need to remove the plate from the front of the magazine and this will give you access to the plunger tube. In order to remove the plunger and spring you’ll need to take one more screw out on the other end of the the plunger that hooks into the catch mechanism. The K26 custom spring is slightly longer than the stock so you’ll need to compress the plunger a bit in order to get all three rods to hook back into the catch mechanism and put the screw back in.

Worked Perfectly

Getting my Hades apart was a challenge, but obviously that wasn't an issue for this spring. Once I got the spring in, my Hades hit pretty much exactly at 120.
