fix your image tags....
EDIT: woha i posted and they worked when the page refreshed...... sweet!
other than that, it looks like a well made gun........
what pressures do you use it at?
EDIT2: omg you posted the working pressure as well..... wow.... im good.... you should get a shock pump to get the thing to 400. you wont be dissapointed.
whats your main ammo?
Im interested to see how you fired it. i cant tell if its a barrel sealing piston valve with a fire extinguisher tank, or if the fire extinguisher valve is the main valve.
and BTW your english is just fine.

Nice gun, I thought you fired it by pressing on the fire ext. handle.

but theres a schrader valve at the back of the barrel on the tee......
mabey its used for filling somehow.......

could he be holding the fire extinguisher valve open while he fills it?
you would think the pressure would just go out the barrel
what's the piece that comes after the tee, but before the barrel?
i'm confused

The thing after the tee is a silver ball valve. Thats probably how he stops air going into the barrel, just closse the ball valve, fill through the shrader, open the ball valve, then press the fire ext. handle, so he can fire it by a handle and long trigger.

my gun is now running at 180psi.
and my main ammo is moped/scooter rolls that used for the vario with a m8 screw.
i mean this rolls.
and im using the fire extinguisher trigger to shoot it , and when i add a penn trought the holes i can fill it .
and the thing before the barrel is a silver ball valve. to close the barrel when im filling the air chamber.

i did not think the people on this forum where so damn stupid.. if you look in the vid you can see the valve
the gun looks amazing, and i think i have to get one of those tanks and make a barrel sealer..
job well done mate!

nice gun
you should make a piston valve for that or buy a QEV
where are you from ? scandinavian countries, netherlands ?

im turkish but live in netherlands.
and a qev cant hold the pressure 400psi is a lot.
maybe a home made thing or somthing.
the trigger have almost the same speed as the qev valve.

lol I guessed where you live from your english.... (becaue it's so good)
the trigger has low flow when compared to a 3/4" or even 1/2" QEV
QEVs can easily hold 400 psi I use mine at 400 and more with no problems.... al-xg have used them at up to 850 psi...
so you can use them don't worry

i searched here for qev's , but the qev's in netherland can only hold max 10 bars thats like 130psi because the piston is made of a thin rubber thing
and the screw thread of the bottle is different , its a thin screw thread and the diameter is too big to use other parts like 1/2 3/4 or somthing like that

QEV's in netherland are most likely the same as anywhere else in europe.... post a pic if you can but I am almost 100% sure it's the same thing....
10 bars thats like 130psi because the piston is made of a thin rubber thing
yeah but 'we' use them
above their rating... and they are fine...
