Seems like a good idea but tell me you all don't see something like this happening. After the obligatory fuck-up.



Oh wait? That's fucking awesome you say? Then let's hope they fail harder then Dr. Robotnik does when facing woodland creatures.

I remember hearing about a gun that shot a shelf propelled bullet that had little to no recoil, problem was that the barrel was too short and sometimes the mini rocket bullet would not achieve sufficient speed and just drop to the ground. Literally useless at short range too.
Those have not been produced in ages. The problem has nothing to do with performance (They are actually excellent), but the massive cost of rounds.

they where beaten by about fifty years. Ever here of the recoiless rifle? It was used in Korea, weighed an ass ton and had to be wheeled into combat, but it was a cannon that never moved, even with out the stabilizers(which we now call "those things that hold the door open"). It was neat, but still not a rifle, so this is the first hand-held one I've heard of.

What you do, is you tie (weld) your gun, to another, backwards facing gun, and fire them both at the same time. Conservation of momentum FTW.

Try 100 years. The first recoilless rifle was tested prior to WWI.

Well unfortunately, the Recoilless Rifles are not a man-portable weapon system, they are vehicle mounted or crew served. One good example is in the movie Blackhawk Down.

Unfortunately though, if you think of the physics behind trying to make a truly "recoilless rifle" that infantry can carry, unless the round launches with zero friction in the barrel and it launches without actually having to deal with "equal and opposite reaction" (I.E. the brass being forced backwards into the bolt, reloading the weapon and propelling the round the other direction), there will always be recoil. If you make the weapon heavier, yes you succeed in increasing the amount of energy necessary to produce recoil, but your body (or whatever is carrying the weapon) has to use more energy to carry it, which rapidly leads to shaking hands, sagging arms, and decreased accuracy in general. This is why the Military M-16's are significantly lighter than competition AR-15's (civilian M-16's), because even though the recoil will be lower with a heavier rifle, you need to carry that thing FOREVER. This is why vehicle mounted weapons (see: M-2 Ma Deuce .50 Caliber machine gun) are heavier than necessary, because a Humvee or a tank can handle the extra weight which will decrease recoil for the gunner.

So yeah, the physics of a "recoilless rifle" with modern technology still does not work with traditional bullet technology.
The "recoilless rifle" is what people traditionally called a rocket launcher or bazooka. It's typically fired from the shoulder and uses the backblast from the round to keep the weapon from kicking. The AT-4 is a man portable device that is considered a "recoilless rifle." The Davy Crockett was a nuclear "recoilless rifle."

If I'm correct, the KRISS is in Modern Warfare 2, but is called the "Vector".

Some other examples involve the .50C Barrett Sniper Rifle (the whole insides move backwards each shot, so there's very little recoil) and the AA12 shotgun. I'm pretty sure all the guns I just mentioned have detailed Future Weapons videos available.

Here's the AA-12 for you:

People were so excited about videos like this, the gun has gotten into a lot of newer shooters, like MW2, Killing Floor, GTA4's expansion packs, Saints Row 2, etc etc.

There is no such thing as a "recoiless gun". For every action there is an equal or opposite reaction. There is still a reaction in these recoiless guns, the only difference is that the gun manufacturers have found a way to make it not throw off the shooter's aim.

Brilliant!
OT: I'm not a big gun fanatic, but lessened recoil sounds dandy!
Well, not for you arm due to the increased weight, but whatever!

The minigun used by the military, is supposedly recoiless, or as close as you can come to it, since it fires the bullets electrically or something.

The Dillon Minigun? No, it uses smaller ammo than it's .50 caliber cousin and it is just always mounted so the recoil is not much more than a vibration.

The M82 Barrett owes its spectacular recoil reduction to that boxy muzzle brake you see on the end of the barrel. What it does is vent gas released from the bullet firing to the sides and rear of the barrel, thus countering a portion of the force from firing. Makes the gun easier for the shooter... and hell for the spotter.

"Recoilless" rifles are nice, my favorite weapon is one (The MK153 SMAW). Having fired several shoulder mounted recoilless rifles I can tell you all that their name is NOT entirely accurate. While a negligible amount of the thrust produced from the weapon is felt as recoil, the problem lies in the fact that you start with 40 pounds on your shoulder to half of that travelling very quickly from the back of the weapon out the front and are suddenly left with 20 pounds on your shoulder. That shift in weight isn't really recoil but it feels similar.
Another downside to the weapon is that since your body is not absorbing the thrust from the projectile, its projected in a cone from the rear of the weapon... potentially producing casualties as far back as 90 meters. Further complicating this is the behavior of explosive force when contained in a relatively small area such as a building. Every wall that a pressure wave bounces off will multiply the amount of force anyone inside that room would feel, so if you were to fire an AT-4 or RPG inside an enclosed space you would kill yourself. Our regulation was you needed at least 21 square feet (a 7'x3' door was preferred) of open space directly behind the weapon to safely fire inside.
"BACKBLAST AREA ALL SECURE! ROCKET!" -Me giving the fire order for a rocket.

Now finally to the original topic, although I'm sure most have gotten bored of my insights and have since moved on. Reducing recoil in pistols and machine guns is always a plus for accuracy; but as far as recoil being uncomfortable or painful, stop being such a wimp unless you're firing something large enough to kill an elephant. 5.56x45mm and 7.62x51mm NATO are not punishing rounds at all, and after popping off a box of twenty 180gr. .300 WinMag shells my shoulder had felt better but still wasn't bad. Worst recoil I've felt was in my Mosin-Nagant 91/30, it shoots the Russian 7.62x54R which isn't too bad until you realize that its a 67 year old rifle with a wooden stock and a metal buttplate.

It also costs more than a helicopter.
So if the time ever came where you needed to buckshot 90 people a minute, your money would have been better spent elsewhere.

Most classed recoiless rifles, are rocket launchers. There are some sniper rifles with floating barrels which can reduce recoil a great deal.

Truly Recoilless guns are possible, but ONLY if the forward momentum is equal to the rearward momentum, that means some mass MUST shoot out the gun in the net OPPOSITE direction to the bullet.

Look up "muzzle brakes" and "Recoilless Rifles".

If the barrel recoils and remains inside the device, all that could possibly do is extend the recoil over TIME, and only reduce the perception of the recoil. Though that can be as good as recoilless.

From the little that I have read about the KRISS KARD, it isn't even claiming to be recoilless, only that is moderates the recoil to redirect it to be a bit more manageable but the gun is still going to kick somewhat.

Remember kids, physics isn't just a good idea... it's the LAW!

NO.

Where the hell did you hear that? A floating barrel is still securely fixed to the rifle but only at one point near the breach, the rest of the length of the barrel "floats" within the receiver. The sole purpose of that is to achieve more accuracy, precision and consistency with extreme long range shooting like at 800 to 1600 meters range.

If the barrel is not touching any wood or plastic, that removes variables and gives the barrel a distinct "harmonic". You may be able to recognise a free floating barrel as after firing it MAY ring with a particular tone for a second or two (though ideally a heavy barrel should prevent that).

Bottom line, when the bullet is fired, it pushed back on the rest of the gun just as hard as a "bedded" barrel, giving just the same perceived recoil.
