No a qev and 3way doesn't give you full auto because if you held the trigger open it will only release air not recycle the bolt

you do find c02 air rifles look at the gamo air rifle, 200 shot's off a 88g c02 at 800 fps with some pellets . Hpa will give you better consist. With more power altho the power you get from c02 (850 psi) is nothing to joke about either . With brass / copper make sure you check the rating and search ...

I don’t think 40psi is going to do it for you dude, it will have to be at least 100psi. Most likely more.. The further the distance the higher the pressure will have to be.. Also is air wastage an issue?? Are you going to be carrying a HPA bottle with you?? Qev's can be very inefficient with air bei...

sniper , sniper rifle it doesn't really matter ... Personally I would consider anything built to be accurate over distance (most likely with scope and bipod ) to be a sniper rifle. For what you’re looking at constructing a Qev would be perfect!! Especially running on HPA since you can reg your press...

sweet as man !! works well, looks good (outside ) lol jks , i love the idea..

So .... were's our video cant wait to see it at work !!

Keep up the good work, nice to see another fellow countryman making his own guns

Right on brother keep it up !! :salute:

hehehehehe - good one

so what would be your suggestions ??

in order to reduce the amount of force needed to open the valve you could make it a partially balanced design Yeah i've looked into this (BTB's - excample) but i couldn't understand how it worked. i need something like his push buttton but need it to be chamber sealing and travel through the "T" up...

hey all sorry it's been a while my computer shat a power supply :? but im back now :D have to ask, will pulling the trigger slow affect its effectivness?? And how stiff is the trigger? Yea pulling the trigger slowly does really affect the effectivness and power which is a little bit of a same when y...

thats a great setup, same idea as most ball valve triggers with a nicely made trigger, sear and spring ..

There are a lot of really nice guns through the french forum , might be spending a bit of time having a look through there .... if only i could speak french

So is there a good way to make a hammer valve for a Qev running @ 800psi ??

Thanks everyone for your kind words, makes me want to do more ... even Brings a tear to my eye :lol: :D I've Started my new Stock which is similar to this one but haven't cut anything for the internals yet as i would like to change the valve.. I don't think it is very efficient, great for dumping, b...

Patto..do be careful..the power behind it is incredible.I had to knock the hammervalve open with an actual hammer. And I had to hit it hard too! If anything fails it will be very dangerous. So would it be a better idea to run the co2 through a reg down to say 400psi and use it that way?? That would...

Sweet as Thank you

So what does that mean ??

Am i able to use an unregulated 12g co2 straight into a 1/4" Qev, while using a hammer valve to pilot the qev, so i can have multiple shots ?? (Shooting 6mm steel bb's )

Does that sound like it would work or would the liquid c02 reck the valve ?

ahhh good point !! my Apologies

My idea is to Use the 12g co2 and reg as above straight in to a Qev
to use in a hammer valve setup , similar to BTB "old shatterhand".

i'll be using 6mm steel balls . (new valve setup for my SSBA barrel )
