First post: New to all this. Vortex Airsoft BBMG

Unread postAuthor: Username » Sat Nov 27, 2010 11:24 pm

Hello everyone! As the title says Im very new to all this so we'll see how I do ;). Ok so basically I've been playing airsoft for 5 years and my favorite type of gun is a high speed (High RoF) setup gun. There is a guy who has played at the same field I play at for years and he uses an Inline Vortex gun (Nicknamed the Flamethrower for obvious reasons) and I talked to him for a while at the last game and he's convinced me to build my own. I have my plans pretty much drawn out on paper so, I wanted to know what you guys think. (Im going to be as detailed as I possibly can in writing).

Today I went out and purchased some 2" & 1" Sch40 PVC and the smallest pieces they had left were 10' so I have that for each size.

Im going for a "flamethrower" look so keep this in mind.

The stock of the gun will be made of the 2" PVC, about 12" long, and have 1 piece on top and a smaller piece on bottom to give more of a stock feeling. A male cam-lock to attach to the "Magazine" part of the gun quickly.

The magazine will also be made of the 2" PVC and will also be 12" long. It will hold approx. 2,200 rounds. The stock will house a real steel AR-15 Buffer Spring with a Plastic (or aluminum, just depends on what I machine it out of) "Plunger" on the end to help the BBs feed into the vortex block.

The vortex block (all this is subject to change if you all have different opinions) will be machined out of a 1/2" sheet of aluminum. The vortex hole will be 1" in diameter. Im going to make it to where it will accept a normal airsoft M249 Hop up and have set screws securing it in place, so If something ever goes wrong, its a normal aftermarket part that can be purchased with no problems. And I'll just screw some plastic (ABS) on the block to make the "BB Shroud".

The barrel will be a stock brass barrel taken out of an old airsoft gun, and has an ID of 6.08mm and have a length of 11"

The outer barrel will be 1" PVC (12" long) and will be surrounded by an 8" long decorative barrel shroud. (Just the 2" PVC with holes drilled in it to look like a heat shield)

I will make some barrel spacers to make sure everything stays solid and wobble free.

So that's basically it. I don't think its to bad for someone whos never done this before ;).

Oh, and I'm going to use a pressure washer handle as a trigger and all of it will be powered via 5lb C02 tank housed in a load bearing backpack. So here's where the questions come in... Where can I find a decent regulator and what hose should I use? (if someone could provide links that would be greatly appreciated) Also what fittings will I need to incorporate this pressure washer handle into the gun? (and fittings for the tank, regulator, and hose for that matter).

Thanks for taking the time to read my book ;) and if anyone has any suggestions, let me know!

This is how I hooked up a paintball tank to a pressure washer handle, there was some epoxy involved but it can be achieved with standard reducers.

Instead of a regulator, why not use a flow restriction between the pressure washer and the chamber? If you're feeding CO<sub>2</sub> though a tiny nozzle, it will keep power down (especially fed into a large BB chamber) and lower consumption, without the need for an expensive and complex reg.
