Why did the US military (or any other, for that matter) adopt

>>28926167
Too expensive.

>>28926167
Expensive and fragile for general issue. Also couldn't be used to mount a bayonet, can't be used as a club. Also, when the air tanks are empty they require hundreds of pumps to get them to full pressure.

The Austrians issued a few to skirmishers and marksmen, light infantry, the SOF of their day, but not to regular line infantry.

Expensive, didn't take abuse particularly well, if the thing breaks you're not fixing it in the field easily

>>28926167
Very expensive. Though i would love to see how far air rifle technology could have gone when designed with fighting a war in mind.

>>28926194
If I recall correctly, Napoleon had air rifles too.

I can't wait to build one of these. But spec'd up to 4,500 psi. A gas operated locking bolt might give more velocity in semi-auto function compared to a blowback design. Not many examples to go by.

>>28926167
The Austrians did. They found out in the ten years it was in general service that it was extremely expensive, fragile, and complex. It was literally ahead of its time.

It couldn't have had much power, but it held a couple shots and was kinda sexy. Mini-Girandoni for a mini-military leader. I'd like to see a modern multi shot big bore air pistol>>28928263

>>28926167
They wanted to and were enamored by them until they saw the cost of buying them all.

>>28926194

Thanks for the post anon.

>>28928174
part of the problem may be how much compressed air gets used each cycle. Not a big deal for gas operated firearms while the working fluid (expanding gas) is in great supply each cartridge

>>28928174
This one in particular was designed with gun control in mind. It'd be an extra step away from regulation in case of da habbening. Currently unregulated in most states.

I could carry a full-auto, suppressed, .72 cal air pistol on a air hose to my backpack even in commiefornia if I wanted to. I think most people interested in building such a thing don't want it advertised for fear of sparking regulation.

Pumping air and casting lead is much easier than synthesizing, stabilizing and granulating smokeless powder with a reliable burn rate and chamber pressure... Once they take away the powder supply shit'll be rough.

>>28926198
Air guns aren't as fragile as they used to be either, modern materials and machining meant that keeping a few valve parts around should be all you need to stay up and running.

>>28928363
Yes indeed, air guns already have very limited capacity and being semi-auto could be seen as a complete waste in this restricted situation, blowback or imaginary pneumatic bolt carrier or not. It'd still be cool and fun as hell though.

>>28928363
However I think the Caselman would put out 2 thirdy round magazines or so on a 1,000 psi fill. A 4,500 gun tank regulated down would be way cooler. A backpack tank would really get things going.

as someone who uses pneumatics for conveying for work, this is interesting to think about

air rifles could theoretically fire a wide variety of projectiles. How come nobody has designed a buckshot shell or saboted flechette for these yet?

>>28928680
where do you get those? also, how much power do you get out of those and for how long?

>>28926167
>1500 pumps

>>28933330
takes way more than that to fire my pop gun, if you know what I mean.

So are these designs and operations plausible IRL?

>>28933519

It's not seen in the pic provided for >>28933495
at least, but if that thing is meant to be pumped manually OR fired from a reserve canister, then it looks like the design might work if the fastener mechanism from the bike pump to the chamber is good. But as illustrated from this side, it doesn't look like the bike pump has a way to recharge the reserve canister in the stock.

>>28926167
Long range effectiveness was very important at that time and a higher rate of fire weapon wouldn't help much if the enemy could be firing on you long before you got close enough to use it. Same reason it took militaries so long to adopt any repeating rifle for general issue. For example, during the US Civil War the Spencer rifle could only effectively be used at about half the range of the rifle muskets that were issued and the Henry rifle at even shorter of a range.

>>28933519
That'd be pretty fucking heavy with all those barrels wouldn't it?

Or does air magic let the barrels be thin aluminum and not burst?

>>28934102
The latter I think, in game it said it was made of bicycle parts.

However, this is the same video game where a dude can run through tunnels with a gas mask on wielding a 12 gauge belt fed DShK

This is the bike gun, unless they're both bike guns. Pretty sure mine is 12 gauge, which sounds like it might be dangerous to the user.

>>28934102
I'd assume they're a type of reinforced aluminum like those used in aircraft to handle the changes of atmospheric pressure when changing altitudes

It's made to be pumped manually to refill the tank inside the stock. IIRC, it fires 15mm steel ball bearings.

>>28934133
>12 gauge Belt fed DSHK
Seems possible actually. I know there are some Ishapore conversions that makes it shoot (IIRC) 12 guage shotgun shells. Problem is it can only carry one round.

>>28934641
that's what I was worried of. There's no means of getting the air from the pump to the reservoir, unless it somehow pushes it backwards through the chamber.

>>28934200
was that actually in metro? never saw one. was it dlc?

>>28932810
they do make air shotguns

>>28934922
Not sure if it was in the original but the bike gun was in the Redux

>>28934200
Would sawing the barrels off at an angle like that be as dumb as it seems?

>>28935004
Yes, all your shot would drift significantly in that direction.

that actually looks pretty cool.

Are any modern air rifles as good as the Girandoni?

20 round magazine, .46 caliber, can empty the magazine on a full tank and all shots are full power?

Is there anything modern that's just as good or better?

>>28935621
>>28928174
This gun
It's full auto

>>28935621
The bitch with it is what happens when you run out if air?

Holly shit what if they made the projectile also the the propeller. Like make compressed bullets
The bullet holds air and once punctured by a hammer, releases all of the air propelling out of the barrel
No more air tanks

>>28936123
wouldn't that basically be a gyrojet

>>28926167
The US gave them to scouting parties.

Better question: Why did nobody ever adopt the lever-action over the much slower bolt-action?

>>28937671

Harder to fire prone I would think?

>>28937671
Lever actions tended to use tube mags, which are not safe with modern pointed bullets.

>>28937671
Reload time probably. They had stripper clips for the bolt actions but I don't think there was an 'effective' way to quickly reload lever actions.

>>28937671
Levers were less reliable, more mechanically complex, and more expensive in addition to the already posted answers
