VM68 Pump, cuz why not.
rear velocity control, spring return pump.
possibly they heaviest pump in existence.
Added some breakdown photos.
I have had the desire for a while. I had a body laying around and plenty of parts, so i took a hammer that was missing the back and ground off a bit at the head to reduce blowback. Took a broken connecter pin, and put it in. Removed the rear piece off the bolt and tapped for the pump handle connector. Drilled and filled a slot in the body. Cut the main spring and moved it to the bottom.drilled and tapped a velocity screw.
The "pump guide" is an old sledgehammer reg that is blocked inside to plug the front asa. I tapped a hole for the hose on the right side and ran it to an old wwp asa.
pump handle came off a nelpot, some kinda homemade job. Capped the front to hold hold the return spring. I did a homemade detent for doubles, and i use a cocker barrel adapter withe 3d detent for rollouts. My buddy Bryson printed the new trigger panels. Thumb screwa for everything cuz they were there
Velocity is 280s after cutting the spring a few times.
