VACC commissioned me to figure out how to make a modular 3K integration that could be attached to the integration rails on the +Bow. With the Airtech 3000 he provided I took a ton of measurements and worked out how best to reduce the over-all size of the internals in order to minimize it, without removing the auto-advancing turret mechanism.
The piece on the pump that advances the turret had to be relocated. The length of its stroke was different from that of the pump, so tracks had to be cut in the side of the shell and in the pump slide.
The pump is allowed to slide forward and back. At either end of its stroke, the pump pushes the advancing piece to each end of its track. The pump slide is further stabilized by the black lip pieces added to the edges of the slide arms.
The unit can be attached to a +Bow using threaded rods, or quick-release pins.
The trigger rod of the 3K will be attached to the lower half of this double trigger that replaces the normal +Bow trigger.
The finished unit with 4-inch barrels and a bungee'd ramrod. Total length is 10 inches.
This took three months of off-and-on tinkering to complete.
And before anyone asks, no I do not want to make another one of these. And no I probably won't make any templates or plans available because making one of these involves some very tight tolerances between many moving parts.
The rest of you simply get to look forward to being shot with it.

NICE WORK! I hope I get a chance to see this at DCNO (crossing fingers in hopes that I can make it this year).

I will raise you one word: DAMN.
Slug you make me want to get one of those +bows each time you show one of those cad drawings. Nice work.

I hope you have some agreement with VACC that he's not allowed to shoot you with it since you made it for him.

Yeah. Three threaded rods is plenty for holding this in place.Does the attatchment system feel secure?

At the last DCNO he used the +Bow I made to shoot me in the face.

Do you mind it we get a pict of it mounted on the +-bow?

Thats beautiful. What material are those barrels? Are they acrylic/polycarb?

Feels the same as a stock 3K, only the grip is much wider.Is it comfortable to pump?

Also, I would really appreciate it if you posted a template for just the turret spacer plate.
But, I appreciate how busy you probably are, and just the picture would be great.

And here's a barrel spacer template. Place on a page and resize to 2.375" in width.

Drill the center 1/4" then super glue onto the stock barrel stabilizing piece. You'll obviously have to drill the barrel holes to match the OD of your barrel material.

The auto-rotation still works, it keeps many of the stock parts, it's small, it's light and it's integratiable. Who or what are you!?

On topic: I really, really, really like that. Maybe you should make one for something like a lnl or a nf. Or make an attachment for a camera or something to see war footage. I don't know, I am just brainstorming.
