Here are some pictures, I will soon test it at 8bar.

It is for airsoft, and looks like that one
I did a first test with ammo at 5.5 bar, for so far good...
Next test at 8 bar!
Pictures coming soon!

Thank you all, How do you plan on triggering your claymore? If it's by tripwire, you want something that needs a lighter pull than a blowgun, personally I would go for a ball valve. I used your advise, I installed a ball valve. You are right, it will be more sensitive... My glue and paint are drying...

Ok,
thank you!

So if I got it right:
I can use my blowgun (connected to "P") for filling my chamber (connected to "A"). When filled, i can use my blowgun as a trigger, the air of my chamber will go through the claymore (connected to "R"); Right?

I guess I can start building! I will show the result!

Hi all, I am new to this forum, and also new to QEV's. (Never worked with them before...) I finally found one, so I'm ready to start building my claymore... But I've got one problem: I don't know how to install this kind of QEV! :oops: I searched for a long time, but couldn't find the answer... Here...
