The diameter of some springs are just a hair too big for some bearing plates on spring guides. It's hard to notice this until the spring is under load (i.e. trying a shot). The piston body will jam/bind the end coils of the spring on the bearing spring guide....essentially locking the piston. Depending on the body it can be a bugger to get apart at this point as well.

Hedge your bets and stick with the same manufacturer for the spring guide/spring.

The limit here for outdoors is 425, and 350 for indoors. I ended up ordering a modify s110 spring, shim kit and a new modify air nozzle. Mod list so far is:

-modify bearing spring guide, bearing pistion head, air nozzle and s110 spring, and a madbull tight bore barrel. I also ordered a new hop up rubber.

Ill be re-shimming the gear box, cleaning and assembling everything. Hopefully this will be keep the gun reliable and accurate.

Thanks for the advice guys!
