Edit, I know it doesn't look good, but I assure you it looks alot better.

This is ready for the next skirmish I can go to. Have fun looking at the pictures. You should be able to figure out how it works...

Operating pressure, 100-200 psi.
Rate of fire, varies from 0-100. It depends on the air flow.
FPS, no clue, but I will update when I find out.
3/4" cap.
1/8" PEX tubing barrel, a nice fit for bbs, tight enough for me to use lung power to shoot them across my yard.

Piccys.


Jsr, the toe is for you.




I know it looks horrible, but it works.




Magazine pulled out.



The main mag and the spare.

I hope you enjoyed looking at these! I will hopefully get a uzi body for it, and a co2 regulator and the whole 9 yards to make this worth the effort put into it. I spent maybe 32 hours on it (yeah I know its alot but hot glue and epoxy and jb weld take ages, plus experimented...)

Reminds me of a ghetto version ofthis.

At least it's covered

I wish I could make something like that. But this is pretty much held like a P90. Its nice and compactish.

Sorry for the double post, but I am officially putting this through its paces against some 300-400 dollar aeg's today. I hope it goes well!

I await the results. A well-made vortex at high pressure should have a comparable rate of fire and range to a good AEG, but not accuracy.

exactly bbmg´s accuracy are miserable

Hahahahaa, it preformed pretty well, except I had to constantly run back and forth about 100 feet to an air compressor, and then back another 100 feet to the base. Other than that, it was alot better than my friends $300 rpk with 400 fps and a rate of fire around 900 rpm. I bulls eyed a enemy at about 50 feet right in the throat with about 10 bb's and he is pretty pissed. Other than that, it has a speed of around 500-600 fps. Grouping varies depending on bb weight, with .02's I shot like a AA-12, but with .20's I was able to shoot with 6" groupings. So its a pretty good gun, but needs more air volume, or higher pressures. Thats all I noticed, except for the fact that instead of cooling as the air passed through, it actually heated up. Dunno why, but at least it worked.

500-600 fps? That seems a bit steep. If you replaced the vortex block with a detent, it would be way more powerful and use about 3 times less air. I like how you used the fire extinguisher, but I really think you should put a detent on there.

+1

If I had a readily available supply of bbs id make a detent bbmg too.

Well, its what was compared to a 400 fps gun, so its roughly that speed. All we heard was pat pat pat pat against the back stop, then pat from my friends sniper.

I seriously doubt your vortex managed 500fps. Don't mean to hate, but that's an absurd estimate.

I agree, 500-600 fps are a lot for a low pressure bbmg without a detent . 0.20 g bbs are light, even with my co-axial rifle at 200 psi I don´t think I can fire a 0.20 g bb to 600 fps with a correct trajectory

Unless you control it, the BBMG's ridiculous rate of fire should more than make up for lack of accuracy, especially at longer ranges with a wider spread.

The good ol' human ear chrony I think you'll need a better yardstick than that.

Well, I don't have access to any chrony, or know anyone who has one that I could borrow, so I won't know the actual speed. I will tell you the most ridiculous number I got from the other people at the skirmish was something along the lines of like 1500 fps... I let them think that, and I won't shoot them down (no pun intended) and tell them that its only some where around 400 fps.

I think 1500 fps is certainly possible with a strong spring-piston airgun with .20 gram bb's. It would hurt accuracy however.
