I'll try to get a video posted in the next day or so. I got a little problem with the firing. Hopin someone could help. if there's too many bb's in the vortex, it will stop shooting. I gotta keep the gun almost completely level for it to work. any suggestions?

Is this the correct orientation of the block?

Really, the covered half should be on top, not at the bottom.

I was told to cover the bottom...

It doesn't make sense, because as it is, BBs below the covered level cannot enter the vortex block.

that one guy who's supposed to be a BBMG expert said to put it on the bottom. so I did what he said.

Is it an inline internally with the BBs being pushed with a spring or is it simply gravity fed like this?



See, the shroud goes on top

there is NO plunger pushing the bb's forward. I was gonna put one in it but I couldnt find a spring big enough. so I guess its a gravity fed inline.

In that case, as I pointed out above, the shroud should be on top. If it had a spring driven plunger then it wouldn't really make a difference, but if it's gravity fed then it will work better as shown in the diagram.

ok I know for a fact that I can get the shroud off...but if there's a chance I cant get it back on would it make a difference?

That is correct. I just did a search in the wiki and it referenced burnt lake. Look half way down the page.

thanks guys so much. I'll try that. with the chance that I can get another shroud back on there...

added a video! check it out!

yeah the shroud should be on top of the vortex block.

Also to address the feeding problems, I would install a spring with a plunger so you don't have to shake your gun to agitate the BBs.

As far as that one guy that is supposed to be a BBMG expert.. he really should of told you to put it on the top. If you are referring to me, then either I was super tired, or you misunderstood what I said. EDIT: I don't think it was me because I would of told you to add a spring and a plunger, to me its a very very crucial part of any vortex BBMG.

Update: It was not me, this was the original thread where you asked me questions and I never said any such thing:

David Vaini's Official Tips For Vortex BBMGs:

Use a barrel that is very close to the size of the projectile. Try to minimize blowby as much as possible. If you are making an airsoft vortex BBMG, make sure to use an airsoft barrel, brakeline has way too much blowby which reduces power and efficiency.

Always have a spring and a plunger, If you cant find a spring, shop online, if you cant shop online, then ask a friend to shop online, unless your country has laws against springs there should be no excuse.

As far as the spring strength, make sure to get a spring that is just strong enough to push the bbs to the vortex block. If the spring is just strong enough then you will not need a shroud. If you couldn't find a spring with just the right amount of strength, then put a shroud or skirt on the top of the vortex block.

When installing the barrel to the vortex block make sure to file the inlet to the barrel so that it "funnels" into the barrel(this will allow for better feeding efficiency). Also make sure to match the beginning of the barrel to match the curvature of the vortex hole.

For the air inlet, either have the hole for the air inlet be smaller than the projectiles or add a screen to prevent BBs to fall back into your air stream.

If you are using a vortex BBMG for airsoft and you want greater range, you can install a hopup. For the longest time there was the notion that it would be silly to add a hopup because it would wear down to fast. This really isnt that true, it doesn't really wear down too fast. Even if it did wear down, you are roughly in the same boat as you would be without a hopup. A hopup is the number one part of a BBMG or airsoft gun that improves range. A hopup when dialed in correctly will also help with accuracy.

yea I went back and read it. I just misunderstood you. lol

sick, it almost looks like an mp40
