I'm thinking about trying to make a sort of open class pump. The idea would be to make a back block for it and attach the bolt and pump arm to it. OR slot the side and attach the pump arm to a sled. Though that would require a long slot down one side.
combine that with a 4 oz co2 tank and a tiny push button switch and I'd have an autotrigger spump.
Thats what my thoughs are. BUT I'm open to suggestions to other cool mods both pump and semi auto. NO SPIMMY CONVERSIONS, I already did that....it's boring. I'm looking for cool spyder mods that keep the basic sear tripped operation intact. What have you done to yours?
Also the vlave chamber is tapped for a sidecar mod but the hole is plugged currently.
THANKS!
