Theonly parts needed is a screw and a nut and maybe an extra spring if you want.
So I decided to lengthen the pull stroke becuse that was the main problem with this gun, the plunger head stops way before reaching the barrel so all the air is not forced out the plunger tube. I moved the cocking pin forward about a little more then a inch using a screw with a nut on the end.
then I sanded down the stops in the pull rails like this, they were just under that hole in the side
then sand down the insides of the shell so the screw won't hit it.
now when you pull it back to arm you can see the plunger rod inside
I put a coupler on and filled the plunger heads holes with hot glue not sure if it will help but it cant hurt.
I then found after arming that the pull did not go all the way to back to original resting position because the plunger rod was hitting the new priming screw so when I pulled the trigger the rod hit the screw before coming to a rest and this was the result.
so the slit in the rod needs to be lengthened towards the barrel(pic comming)
Now it gets ranges like a BBB if not better, I think this gun has a stiffer stock spring
