Grossly ineffecient. But the intimidation factor is pretty amazing as you are engulfed by your own homemade smokescreen!!

Powerfeeds only slow down the feed system. Those are more for blowforward guns to minimize the effects of excessive blowby gas.

Did you just modify the sear to go cyclic? Thats probobly a cycle rate of 25-30? Not much will feed that fast, though it would be awesome to watch.

I think this is the VM with the dewalt gripframe?

Has to be done:

I'd forget CO2 altogether and go HPA. No chance of freezing or shoot-down.

Dont forget a much larger tank! your gonna want a huge one to deal with that kind of setup.

liquid on a 24oz is one of the best solutions I can think of.

still working on it. its shooting full auto at about 4-5 balls at a time. Still waiting on the q loader. Hope fully that is gonna feed it fast enough.

crazy but I am using a COLT 1911 handgun spring, took off the bumper, more friction to the bolt by sized o rings and few other small details to make it work. pics and video soon to come...

You need to slow down the cyclic speed.
I had a VM with Full auto, But it was controlled with a Finely adjusted Pneumatic circuit. This is essential.

The only way I could think to make a Full auto mechanical VM to function would be to lengthen the hammer stroke, Beef up the detent, Modify it for Vertical feed off a halo, and run it off a 1200 PSI air america tank, with plenty of flow. A stabilizer will only slow the flow to the valve.

Modifying the valve would also help, But this takes care. The idea would be to enlarge the porting between the bottom and top tubes, And to port the valve all the way around, slap it in a lathe, And turn a slot all the way around, like a modern spyder Hi-flo valve. Of course, at that point, some flow modification to the backend of the valve would be required to reliably recock the hammer. Drill a 1/16" hole through the back of the valve, and use a setscrew in the body to tune the recock gas.

After that, Bore a LPC into the body if there isn't already one there, and put a gasthrough grip on the front ASA, or a hollowed EXC to keep a steady supply of gas available.

Doing the buffer removal would help as well, Top it all off with a Victory halo, or a Qloader, and you're almost there.

I'd suggest a stock, and maybe a Bipod. The recoil on this beast is going to make keeping a steady shot Very diffacult.

I got it doing 5 round bursts with no broken paint but if I hold it down to spray I start to break paint every other.

What are all of the ways to slow down the cycle? Just want to see if there is other ways that I have not done yet...

thanks fellaz!

[WilD]

what about increasing the mass of the hammer to slightly slow its cycle rate? My understanding is that is how some older real machineguns adjust ROF.

If that approach will work in this application, you could drill out the hammer (in a non stressed location and fill it up with lead.

[Azzy]

Lengthen its travel, or increase the amount of gas going to re-cock.

You running it on liquid?
