Why are there any military pneumatic rifles?

>Compressed air isn’t as efficient a means of storing energy for use in kinetic weapons when compared to gun powder.

Plus most air guns have a problem with literally freezing up from the release of compressed air. Kind of like when you use a can of compressed air duster to clean out your computer.

That said I've often wondered if someone might be able to find ways around those issues. But ultimately you'll unlikely to make a weapon that's better than a conventional firearm.

>The Austrian army was issuing pic related with a 20 round magazine in 1780. Why wouldn't the types of troops who use suppressed weapons be interested in something even quieter?

Well the Girandoni ended up not being a good as as a conventional firearm.

But that said I've often wondered if someone might be able to revive the old Caselman air machine gun. It's probably not going to be really any better than any gun you could possibly make. But it would at least be an interesting new design. And hell, you might end up being able to make something that might be as powerful as a .22 LR SMG like the American 180 tray fed SMG.

Not to mention it wouldn't even be regulated as a firearm in the US.

Why use compressed air and not a gearbox?

More moving parts that can fail.

>Not to mention it wouldn't even be regulated as a firearm in the US.

Exactly. Of course you'd still have some issues with over cooling, especially during sustained fire. But I think those issues could be worked around by an enterprising machinist.

just make it with moving parts that can't fail

I wish the guy who engineered my 540i thought of that

Because air guns are literally for kids. Grow a pair and go buy a fucking gun.

Like 50 pumps with a three stage high pressure pump, a bike pump wouldn't do shit.

I have a semi-auto PCP rifle, I just got it so I haven't used it that much yet, but I haven't had any issues with it freezing even with twelve shots in a few seconds.
I read that with co2 guns you should wait ten seconds between each shot to prevent the cold gas from affecting the gun, but I haven't had to do that with my PCP guns.

I haven't bothered with a PCP of any sort myself. But I imagine that with a semi auto design you're not going to have that much of a problem with over cooling. But something operating in full auto is more likely to have cooling issues.

dude, a modern air gun would use psi in the thousands, possibly even 10,000 or more psi

regular guns produce up to 50,000psi barrel pressure

You know you're talking to a complete fucking Mongoloid neck beard when they bring up the girandoni air rifle. Especially in a gun control context. It's not actually a good example of anything at all, except baby's first gun history lesson

This thing had about the power of a .45ACP, good out 100 yds. Also, standard kit for these was 3 air reservoirs and a hand pump to refill them. Those reservoirs were good for a full magazine each. Ian did a video on one, iirc

>possibly even 10,000 or more psi

I wish, most use 3,000 psi or less. The newest .50 caliber that just came out uses 4,500 psi, they advertise it as the most powerful production air rifle, and I really want it.

The real unspoken advantage here is that it eliminates the need to procure ammo. Which is the biggest hurdle that people in nogunz countries have to overcome in order to get a functional homemade gun.

Why not a pressurized flammable gas, butane or propane like the airless nailguns. Shit they probably make about as much energy as 22 short with off the shelf parts. It wouldn't be quieter by much, and it would be weaker than powder, but much more efficient than air with no freezing problems.

Thank you. FPBP

Because they're inefficient. Every now and then some new gas guns are tested and they always come up short in military applications. For a variety of reasons black powder cartridges are better: biggest prolly being reliability, mechanical simplicity, and ease of supply/storage.

There's some very limited use by spy guys, mostly Russian/chink/best gook etc. heavy 9mm subsonic rounds through a surprised weapon are just as quiet and much simpler/more reliable.

Because it's pressurized flammable gas you idiot.

This is literally an airfag thread trying to make airguns seem like a legitimate weapon. Goddamn Australians.

Freezing issues only noticeably happens on CO2 powered airguns, I think

tfw air rifles, airsoft toys and paintball guns are treated the same as .50bmg bolt actions,
which people are pushing to recategorize[see: ban],
and semi auto .22s are unobtanium for 99% of the population,
and if you're caught plinking on private property with any of the above which you shouldn't have,
you'll land in jail or at best get a massive fine if you have a good lawyer
