Piston Jamming.

[Moose87]

The piston in my Version 2 GB for some reason doesnt sit right and when it slides back it seems to go to one side and jam on the hole and the back of the gear box and jams it up.

 

Anyone had this problem before or can think of a way to fix it?

Sounds like the spring guide is broken. If its factory parts. If there are upgrade parts, a few more things can go wrong.

spring guide seems fine.

It could be:

 

Your piston may be faulty or badly made

 

You haven't aligned it correctly

 

Or your spring is quite bad and it's overlapping when compressed
