Did you know that there is a military-grade paintball gun? The FN 303 is used by Army Military Police as a less-lethal way to subdue an aggressor, and to literally mark punks in a crowd who step out of line so they can be dealt with later. Typically the 303 is used in guard towers to help track prisoners who cause trouble but don’t require the use of lethal force.
This may sound like a sissified way of dealing with trouble, but it’s not. The 303 packs quite a punch. It doesn’t fire the usual gelatin rounds that you find in civilian markers. These rounds are made of a hard plastic. Have you ever bought a pair of fake teeth or little action figure out of those coin-operated vending machines at the grocery store? The rounds are made out of the same plastic as the capsule those toys come in. When a round impacts a surface at 300 fps you can actually hear it shatter.
The paintballs also have bismuth in the capsule to add to their mass, making them surprisingly accurate at distances of up to 100 meters (328 feet). In addition to several types of paint, pepper spray rounds are available that contain 10% OC. 
Needless to say, they leave a bit more than the welt that you might pick up at your paintball range.
The rest of the weapon ranks with commercially-available markers. It has a folding buttstock, 3000 psi CO2 canister, and uses a 15 round, drum-style magazine similar to what you would see on the old Tommy Gun.
Chances are, you’ll never see one of these in real life. But if you do, do me a favor and go after that guy… you know the one: he’s shows up when you’re playing against your buddies, except he’s got a weapon that shoots 4000 rounds per minute at 450 fps. Get that guys for me.

Have you ever heard of the FN-303 before? What’s the most awesome marker you’ve heard of? Let us know in the comments!
This weapon is not non-lethal, nor is it accurate at 100 metres.
In the case of the killing of Victoria Snellgrove http://en.wikipedia.org/wiki/Victoria_Snelgrove ,
the policeman who was aiming at a rioter was not even aware that there was a bystander. She was killed when the FN303 pepper capsule penetrated her eye and broke the bone behind it.
