SSG10 Wasp Piston and Flux Trigger

[Ayeko]

So hey guys,

I got a though problem with my new wasp piston.
I ordered a Rapax RMS 3+, Wasp Piston, and Dampercylinderhead for my SSG10. With the stock piston it works fine, but with the Wasp I need to cock it really far behind like a Overpull. Also i need much force and can’t do a slow pull….
I got the Fluxtrigger. Could this be a problem? Sniper Mechanic said he tested the Fluxtrigger with the wasp. 

Iam lost with this problem, as I have no more points to search.
