Why did the US military (or any other, for that matter) adopt a repeating air rifle like the Girandoni? It seems like it was superior to the single-shot muzzle-loaders of the day.
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.
.72 cal 18" barrel
The 36" one gets ~1000 lb.ft and ~1000 fps
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.
Big bore kits for Crosman 2240 type pistols are where I'm gonna start
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
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
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.
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.
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.
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.
>full-auto, suppressed, .72 cal air pistol on a air hose
I want it to look like this
air rifles could theoretically fire a wide variety of projectiles. How come nobody has designed a buckshot shell or saboted flechette for these yet?
So are these designs and operations plausible IRL?
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.
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.
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.
It's made to be pumped manually to refill the tank inside the stock. IIRC, it fires 15mm steel ball bearings.
>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.
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?
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
