    VM 68 Pump

    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 Click image for larger version

    Velocity is 280s after cutting the spring a few times.

    Add a steel trigger shoe to it, because even heavier!

        There's so much more that I need to know. When did this idea come to you? What other insanity have you been hiding from us? I want pics of the custom parts. I want write ups about the process. I want go pro video of it in use. I want...I want....I want.

          You shamed me into clicking on stuff and reading things. It makes more sense now. Doesn't change my wants, but makes more sense.

        I thought about trying to pump my VM just because. That is Rad! You should do a write up on it.

                    Update: Played today and it shot great. Didn't break any paint and got a few kills. Super consistent over the chrony with 387 for 5 shots. lol after dialing down my dial a welt, it shot 280s.
                    Just need to tighten up the asa as it moves around way to much.

                      Was witness to the awesomeness of this gun. She was hungry and accurate. So cool.

                    That lapco adaptor is a dream lol. Haven't seen one in like a decade.
                    You might want to try an automag spring conversion. Could make it less kicky.
