Haha...finally some competition!!'
Clean looking piece of kit you got there.

How can one get 3 seconds of firing out of that little chamber??
You keep it hooked up to the compressor don'tcha??

Btw..My MG is now a lot more powerful.I got a wider hose on it and shortened the rise tube.

Killah, yours would be more powerful with a bigger chamber, I think :roll: , but I'm not shure that would look better as well.
Nice gun!
Don't even mind coming second after this gun.Good to see more Marble MG's.We have the same taste it seems.
More of a hardcore- no BS -style of guns.

Does it make a nice BRRRRRRRRRRRPP sound???
(edit) sorry about the long post but I have some more to say:

1.How do you control bursts?? Doesn't the sprinkler valve just stay open??
2.Putting the mag a little to the side would make aiming easier
3.I have a higher rate of fire na-na-na-na-na!!

Well anyway..I still like it!!

it seems to me that it is either a semi-auto or burst fire... could you please clarify?

salad, It was still in the works, untill my grandma gave me some money (aghh the pleasures of a nice grandma)
I will get a longer mag soon, but untill then I'll use this. I have only tested it to 40psi and the kick back is amazing! The barrel is a 16mm diametre peice of poly pipe.

$40. Most of the parts are metal, and metal is cheaper to buy that PVC and other plastics were I live. I tested again at 50 psi and decapitated a coffee can. Fricken wow.

Yea the metal 25mm tee was $4 bucks and therefore makes up one tenth of the cost (I think???)

Oh and if you look at the top of the valve, you can see were I plugged the thing that used to be the flow control with a screw and teflon. The reason was because the top of it broke off when I was trying to do the NO DRILL VALVE MODIFICATION by carl. The top broke off and made the damb valve LEAK. So I pluggged it. Works fine. :D

I will answer your questions. 1. the sprinkler valve will remain open untill i realese the blogun.
2.I have moved the mag to the side, because you said that. It is now spring fed.
3.My rate of fire, 340 rounds/min, was measured at 30 forking psi.
I'd say this gun at 120psi would out-do yours easily.

So the sprinkler closes immediately after you release the blowgun?
That's pretty cool!
Can't wait to see a video at 120 PSI
