If I can offer an option for a less accurate, high ROF flame thrower/airsoft replica? How about using automotive brake line as the barrel, then putting a small and gradual bend in it that meets up with the inside of the flash cup towards the back end of it? If you did that, the BBs could start a centrifigal spin around the inside of the flash cup, coming out in a cone effect similar to the spray of a flame thrower. Instead of one stream of BBs, you could end up with a wide area of influence from them, shortening the effective range of the replica and making it possible to use it more like the real thing was. If you used a vortex cup for the loading mechanism, you would still be able to use the back pack tank system that you have worked out, which would keep the realistic look up there pretty good. Just an idea, take it if you want.

Actually by shortening the barrel to about 5 or 6 inches (instead of 16) the bb's will run through a wake of air inside the barrel then enter the outside air and deviate wildly. This happens on my .50 cal. There is a cone of fire about 20 feet wide at 100+ feet. If the inner barrel were the length of the gun (about 4.5 feet), the bb's would be a straight stream. (It would also be a bear transporting the .50 cal with the barrel attached.) ww2aa.proboards.com/index.cgi?action=display&board=general&thread=20&page=1The bb's enter a wake of air after leaving the inner barrel. The "cavitation effect" is the air swirling around inside the outer barrel and the air swirling around outside the outer barrel. The bb's enter two air masses and deviate from a straight line. ///ed///

Man, the only times I can recall ever hearing the term "cavitation" was watching "Down Periscope", LOL! Sounds like you got your desired result, don't suppose you experimented with different length/diameter outer barrels to see if it increased or decreased the effect? That would be some interesting knowledge to have.

That is the pinnacle of pyromaniac inspired toy weaponry, and I am proud to say I saw it. Haha, but seriously that M2 makes me wanna pull together a USMC loadout, but I'm working on my Nachtjager loadout right now. Although, according to Call of DUty: World at War, Germans use the M2 too, haha

Yeah, also, I would be willing to pay any amount of money (within reson) for one *wink*. And, just to offer my rather simplistic solution to the problem, why not just turn the regulator down? less pressure means less FPS and less range. Also, I really like the flash cup idea. Good luck

Have too many projects going. This flamethrower, M3a1 grease gun, another 81mm mortar, a bowling ball cannon (aka chicken gun), Mk19 (internals from a jack hammer), Swedish-K's, and another bazooka.

Ed, what are you using as a base for your swedish k's?

The internals will be AGM MP40's, the body will be scratch built from electrical conduit tubing, and 20 gauge steel, welded body. The body will bolt rite onto the gearbox.
The grease gun build basically paved the way for the "fit, form, and function" in fabricating the bodies. I will post more pictures of the M3 and how simple it assembles n a few days. I wish I had more of the caulking guns, because they saved so much build time, and are cosmetically correct for it.
(Back on topic)
The flamethrower is cosmetically complete. Originally I was going to mount it to a packboard, but I may end up building a frame in the design of the original. Due to it's super high rate-of-fire it is going to be a "show and tell" gun. Because even I, would not want to be shot at with any closer than 125 feet. Would be awesome support weapon if used from the top of a building.
(I will get a video up of it firing.)
