Stock TM piston heads are held on by a screw on the front. Remove that and the assembly will come apart.

i dont see no screw!? am i blind?

what about screw inside the piston. Look down the piston where the spring goes. Any screw there possibly star shaped head.

Ktown Militia · July 17th, 2008, 23:59

no, its just circular

Take a pic so we can see this naughty piston head and figure out whats going on. Gotta be a screw there somewhere.

screw from rear

Screw inside then. Except the spring is in the way. Those ones you screw the entire piston head off. You sure it's spinning? Not just slipping from grease? Try a towel or rag of some sort with those channel locks.

You'll have to start "digging" until you reach that screw. It is right beneath that small pin hole.

I think you got edit: screw from front but can't see it.

just like this for sig at step 23

can you hold the spring and piston then try turning the piston head off?
"twist it off counter clockwise"

i think i found the screw beneth the pinhole. but the fuckin thing is stubborn as hell

OT: Your lack of piston head holes makes me wonder how the oring can get good compression.

I don't know if digging in through the front will cause irreversible damage or maybe you can just fill it in the dig hole with epoxy or hard glue?

I think you can just get it apart by either pushing the spring to cause resistance to prevent the back end parts from turning while you twist off the piston or stick a thick scewdriver to screwdriver into the piston head hole to hole the back end parts from turning while you screw off piston head.

Good luck. Hope it comes off.
