Umm, I've never really used a CO2 tank before but what I've seen been used is CO2 Tank 8-20oz regulated at 120psi. I'm assuming your using airsoft 6mm rounds.

Any chance you could stick up a video?

Yes, I'm using 6mm bbs and 125 lbs of pressure from the compressor. I would like to go portable with it. When the weather gets better I'll post some video.

A very nice, compact bbmg. I could even consider making a bb hose after seeing things like this.

Depending on how portable you want to go, you could use a small compressor with two large PVC tanks and a car battery or somewhat.

Good build

Great work man!, Looks awesome= I need to get my shit together and start making BB Guns again and personally love the look of the MP5(allways have,Esp the MP5K). Once I figure out an easy to make and functional BB Feeder I'll be making an MP5 type bbmg myself,After trying that Vortex Cap,an Inline Half Circle+ inline Full Circle a while back and none of them would feed the Steel .177 bbs!! no mater what I altered?.
anyways enough of my ramblings ..... nice gun

Did you put shields on your block? Haven't had any problem with mine. I think I'm going to make a portable backpack out of a 4 in. pvc tank and run it with a 12 volt compressor and motorcycle battery. Harbor Freight has a 12 volt pump that pumps 300% more air then other that style.

@django..

I'm beginning to wonder what you are doing wrong.
You got it right earlier..

I dont know Brian,I tried everything on the last 3 that just would not feed/fire= with shrouds and without,different blowguns,half circle/full circle Blocks, moved the Air input to varying positions, differering Chamber sizes,with plunger and without but nothing fed??. Because of all that ive never made another I keep thinking its something to do with where I was placing my air inlet nipple or something as it was like none of the guns were creating a vortex or whatever to make the bb's aggitate?.Most of you lot seem to have no issues with making working BBMG's?, Im not new to this either so puzzled as to why my last efforts wouldnt Work?, My old "cloud" DESTRUCTO Pistol and RAZOR" Full Vortex in T- Piece" rifle work fine..............

EDIT: Brian I just tried to use a Qev feeder like you have used and tried it out lungpowered like you sugested to see if it works and the bbs in this did not want to spit out al all either!?? my Qev ia 1/4" and looks exactly like yours too ARGHHHHHHHHHH!

If it doesnt work on lungpower, this doesnt mean that it wont work fine on higher pressures.
BBMG's draw alot of air. Are you using a proper air feed? (compressor or big pressure tank)

Oh, and is really NOTHING coming out of the barrel besides some air? Are you sure the bb's actually even fit?
