Pneumatic arbalète

That is awesome, just would not be legal for record fish in the USA.
Thanks for the link Marco.

Cheers, Don

Why is that?

Subsub, if I am not mistaken, the rules state that fish entered for records can only be taken by guns that rely on a physical loading technique. So using a gun which is powered by stored compressed air like a Pelletier or Mako2 CO2 gun or another gas is not allowed. Even for just recreational spearing, they are not allowed in certain countries.

Here are two pics, both borrowed from Maco2's website showing compressed CO2 guns. First one is the Pelletier and the second, the Maco2 which is a modern take on the long gone Pelletier:

But I don't think the gun Marco linked to above uses stored, compressed air. It is basically a traditional oleo with the reservoir moved to under the handle. Simple as that;-)
With that comes the benefit of being able to raise the barrel to improve the sight line, slimming down the gun for better tracking and, according to their claims, less of a bottleneck for the air to go through.

I have a gun in mind mind that is pushing some of those things, too, and a few others but it is still thought of as a traditional gun with the air reservoir surrounding the shooting barrel. But still, with that design, you can push the before-mentioned parameters quite a bit more than anyone has done so far. Let's see if I get around to making it.

Not a muscle loaded shaft. Even a pneumatic gun is a air spring the muscle loads.
Compressed air guns are also illegal in Mexico, even if some get away with it.

looks like a hunting rifle....and a lithium battery powered impact driver.:laughing:

from the title I had something totally different in mind.

Ah, yes "muscle loading" - that was the phrase that I escaping me;)
I do still think the gun in question is not a CO2 gun but a traditional pneumatic in terms of function.

I agree as I see very little bubbles on firing, just the normal captivation.

years ago my friend JL Tralongo has renewed and relooked the sixties Pelletier gun
you need to fill the little tank with compressed air...
a pretty powerfull gun!

Just to make it clear to others - the gun in Virgil's pics are of the CO2 Maco2 gun (you can use compressed O2, instead of CO2). The gun in the Marco's original post is not a CO2 gun;-).
