About: I like turning boring things into awesome things! Usually on video.

This is a type of cloud airsoft gun - named so because of how the pellets are blown around the reservoir before being fired out the barrel. Since there is nothing mechanical to get in the way of the workings of this gun the rate of fire is extremely high, an estimated 50 rounds per second. It would make a great airsoft turret to be mounted on the defensive wall of a home base.

The price of materials is just over $50 assuming the builder already has PVC primer and cement.

    Adding to that, the tighter your barrel is around the bb, the more air can build up behind it. You can get 7mm inner diameter pipe made of carbon fiber on ebay for like $10. Just ordered some ill tell you how well it works. ;)
    So exited

    Real nice design. Im currently making one out of abs. Also adding a portable backpack (much like yours) but that has a small compressor built in for unlimited air.

    what type of weapon would this be considered? I know its not a legitimate deadly weapon when used as intended, but i want to know if it is legal in Pennsylvania.

    I think this is a very nice design, I plan on making this and putting a bipod and swivel to camp out. One way to make the ammo last longer is to put a small door (sorry I forgot what the name of it is... Latch?) connecting the ammo reservoir to a fairly large "hopper" and when the ammo runs out in the resovoir just open the door and let a small amount into the resovoir. Vwala!

    What do you think about putting on a guard in the front, just like the Mobile Turrent in halo with maybe card board, plywood, or 1/5 in. Tin plate cut exactly like the guard in Halo?

    Hi, I saw most of your videos on youtube and was wondering if you could make an 'ible on how to make a better "Magazine" which could maybe(I really don't know) incorporate a one-way valve or something that feeds the bullets more efficiently i.e. a more guaranteed feed,because the mine dry fires quite a lot, also how long does yours last pressure wise?

    What brand of 2 inch end cap is it? The end caps at my local Lowe's all have a curve in them and can't be glued together.

    going to try and make a cqb mp5 using this type of propulsion. by the way what is the average fps?

    hey I want to make two of these and turn them both sideways and connect them both to make a mounted, two-barreled, gun for my airsoft coarse that I am building. Is it possible to do or will it have some issues?
