MMK-3 French QDV airgun

[Mimikool]

Hi all !

I've just seen the french airgun, of Driveround3, so i hope you will not be disappointed ^^

It's a simple coaxial QDV airgun, i shoot marbles and compressed aluminum paper.

I make a small butt just to have a good grip, it's not really clean but i don't want to work on it, i've a 1"1/2 qev airgun witch will be finished during this holidays.

It work at 15bar (200psi) for now, but 20bar (300psi) when i'll have my freege coompressor.











I've tried to make a rifled barrel, but only in muzzle, and it's inefficient, i'll make another but fully, when i'll build an HP qdv canon from my first that a ever present here.

Nice rifling button.

One thing I notice is that a lot of you French airgunners dress up your cannons with wood, but never stain it?

Beautiful cannon, nonetheless. Nice to see more people building with hand-built parts and valves over ready-made QEV's or irrigation valves.

HAHAHAHA This is very cool still! I want one

Very nice, any chance of seeing the piston itself?

A nice build indeed, but I don't see the advantage over a simple coaxial design, regarding opening time and handling.

A short "fat" chamber and inline ports would be the better choice for a QDV style valve.

Thanks all

For the wood part i apply a cleancoat, or else it stains yes, as my first airgun's butt.

For the piston i haven't got photos now, but before. Today, the space between ths two seat is smaller, and the o-ring is now directly bonded at the large washer for the seat of the baril (at right in picture).

Confounded language barrier. I was asking why nobody ever applied a colored wood stain?

[Mimikool]

Oh, sorry, google translate is so bad... But now i'm not sure to understand, but no we prefere not to paint.

I thinks, a lot of us want to keep the wood color, it's more beautiful, a mater of taste

I don't want to create a new topic, so I present my airgun MMK-2 here.

It will work at 40bar (580psi), but for now, only 10/12bar (150psi)

Nice airgun

why did you put a ball valve at the end of the chamber???

[mark.f]

If I had to guess it's a safety thing. At any time he can completely dump the chamber quickly without having to discharge the launcher.

Underbarrel grenade launcher

Mon dieu, that valve is beautiful!
Why must the french do it so well...

[Mimikool]

Thanks

There is a ball valve at the end oh the chamber because, before, i've put the shrader valve here, on the valve.

But after i replace it behind the piston on the ball valve as you can see

I haven't got cap for now, so the ball valve is good as i don't put hight pressure.
