This guide is courtesy of Das Rabble Rouser otherwise known as Delta with a few of my own touches put into it to adapt it to roleplay purposes.

Das Rabble Rouser
It seems weapons especially firearms get really hyped up in the media. Various rifles are called assault rifles, hunting rifles are classified as sniper rifles, semi and fully automatic are thrown around and said in such a way to make it sound scary. I'm just going to throw out what I know. If someone reading this doesn't know much about firearms I hope they can learn from it. Some details might be fuzzy, but I will try to be as accurate as possible. If you want to learn something specific check for bold phrases used to mark each specific topic.

First off Future Weapons and Ultimate Warrior are shows meant for entertainment purposes. I've heard they can be total idiots when it comes to getting their facts right. All I have to say is don't take them too seriously. Take it all with a grain of salt.

Clips and Magazines are ammo holding items used for loading weapons. Usually when someone talks about a clip they are really talking about a magazine. Some people make a big difference between the two. I think if you know what is meant that is good enough. Still I might as well cover it. A magazine is what loads the ammunition into the gun itself. It is the ammo belt for a machine gun, a cylinder for a revolver, or the banana shaped box in an AK47 are all examples of magazines. A clip is used to load a magazine. Many older weapons had a magazine permanently attached to the gun itself. A "stripper clip" was used to slide several rounds into the magazine at once rather than having to put in 1 round at a time. If you are in doubt refer to the picture below.

Bullets are the projectiles fired from guns. Yes I know any idiot can figure that out. The thing is the bullet is sometimes mistaken as being the entire ammunition unit. A single ammunition unit is often called a round or cartridge. A cartridge consists of a projectile (the bullet), propellant (the gunpowder), the primer (the thing that sets off the gunpowder) and the casing (the metal tube that holds everything together. The diagram below shows everything.

Caliber refers to the diameter of the ammo. It is sometimes measured in imperial and other times in metric. Imperial is in hundredths of an inch, or in some cases even thousandths such as .45 and .223. Metric is in millimeters such as 9mm and 7.62mm. If you're just talking about guns that's all you need to know, but if you actually want to own a gun you will want to learn the specifics. For example there is .22 short, .22 long, and .22 magnum. All three of them are .22, but they aren't necessarily the same. A .22 short won't hold a '22 long or magnum. The same with 9mm. There is 9mm parabellum is 9x19mm while 9mm Makarov is 9x18mm. If you were to try and use a Parabellum round in a gun that takes a Makarov round you would find the round is too long. One millimeter doesn't seem like a big deal, but it can make a big difference.

Shotgun calibers are measured differently. There is the .410 which is 41/100 of an inch like I discussed earlier. Other than that shotguns are measured in gauge. The smaller the number the larger the diameter. This is because gauge is measured in fractions of a pound of lead. 20 gauge for example is the size of a sphere of lead that weighs 1/20 of a pound. A 12 gauge is the size of a sphere of lead 1/12 of a pound. That's how the smaller number makes a larger caliber.

Automatic Weapons are a big hot button for the media. An automatic weapon is a weapon that automatically reloads itself after it fires. There are Semi Automatic and Fully Automatic weapons. Semi automatic weapons are a weapon that will fire once and then reload when you squeeze the trigger. If you squeeze the trigger and hold it down it still only shoots one time. If you keep pulling the trigger it will keep firing until you run out of ammo. Fully automatic weapons are weapons that can keep firing and reloading. If you hold down the trigger it will fire then reload then fire and reload again. It will keep firing and reloading until you release the trigger or you run out of ammo. Fully automatic weapons are heavily regulated so to legally purchase one is difficult and very expensive. This video is a good demonstration of the difference between the two.

Assault Weapons are a difficult classification of weapons. Different sources have different definitions. The media has a tendency to use this term to scare people. The assault weapon ban of 1994 classified an assault rifle as a semi automatic rifle able to accept detachable magazines with two or more of the following features.

1. A folding or telescoping stock. These are stocks can reduce in size making a weapon more compact.

2. A pistol grip. These are grips that extend below the stock of the rifle giving you a better grip. A firm grip helps you hold your rifle better making it more accurate.

3. A bayonet mount. This is a mounting point on a long gun where a large knife can be mounted so your rifle can be used as a spear for stabbing. Flashlights can also be mounted here.

4. A flash suppressor or threaded barrel to accomodate one. When you fire a gun some flame spits out the front. A flash suppressor disperses this flame making it harder to see.

5. A muzzle device which enables the launching of rifle grenades. That's just a fancy way of saying a grenade launcher.

Assault weapons ban also extends its definition to pistols and shotguns. Long story short if it makes it easier to kill people it was on the list of banned features. Features like high capacity magazines can be understandable, but some features are just stupid like the unloaded weight of a pistol has to be less than 50 oz or a pistol grip on shotguns.

In a nutshell assault weapons are just guns that "look scary".

Silencers are a common name used for a sound suppressor. Sound suppressor is the official term used. They are popular in video games and movies. When you use them in video games and in movies it should be noticed that you almost always hear the guns going off anyway. It is much quieter, but it still makes noise. For some reason there is a misconception that they make the gun completely silent. Such is not the case. A sound suppressor is a chamber on the end of the gun for expanding gasses to expand into. It works exactly the same as a car muffler.

This video is a good comparison between the two. It should be noted that while the suppressed gun is still much quieter than the non suppressed gun it is still louder than what is shown in the video. These guns are .45 which are pretty loud in person, much louder than indicated by the video.

Sniper Rifles and Hunting Rifles are similar weapons. Hunting rifles are sometimes identified as sniper rifles. The two are more or less the same. If you watched the video in the Automatic section he explained the difference a little. The main difference is how the name sounds. A hunting rifle to the average joe is an average weapon while a sniper rifle is a high powered weapon that can easily kill in one shot. Sniping tactics were based on hunting tactics. A person does their best to remain undetected while they search for the animal they want to kill. When they find the animal they carefully place an accurate shot to a place on the animal to kill them in one hit. Actually the term "Sniper" refers to a marksman who was accurate enough to shoot a snipe. The same is the principal behind sniping. Since hunting relies on accuracy the weapon is designed to shoot accurately. An actual military sniper rifle isn't as easy to get ahold of but a good hunting rifle can be used for sniping all the same. I don't say this to scare you. The truth is with all the hunting rifles out there if they were really a threat there would be a lot more snipings then there have been.


Less than Lethal weapons are weapons designed to stop a target without killing them. These are tasers, stun guns, sticky shockers, beanbag shotgun shells, rubber bullets, and many more weapons. They are sometimes called non lethal weapons, but that is a misleading title. If improperly used it can still kill a target. Still they are designed to take down a target without killing it.

In Conclusion I hope you have learned something from this guide. When I mentioned to take shows like Future Weapons and Weaponology with a grain of salt the same applies to this guide. This guide is not absolute fact written in stone. I mean for this guide to be taken seriously though.

Sound Suppressors "Silencers" Extended

Like Delta said sound suppressors are nothing more than a muffler that essentially turns down the volume on a gun but doesn't entirely silence the weapon.

To truly silence a firearm, the bullet has to travel slower than the sound barrier (768 Miles Per Hour) and the suppressor has to be adequately large enough to muffle the initial "bang" from the pressure of the propellant burning behind the bullet. The smaller the suppressor the more you hear the initial "bang".

This being said the only cartridges that I know of that fly slower than sound are "subsonics"

Literally every cartridge known to man can be loaded subsonic but keep in mind that with a lesser powder charge the overall energy in the bullet travel decreases. A subsonic .50 BMG is possible but expect it to only go as far as a pistol round and hit like a .45 ACP and not the big anti material round it is in standard loadings.

When accompanied with an adequate enough suppressor, subsonics are indeed almost as quiet as a whisper. The DeLisle rifle is in my opinion the most quiet firearm in existence when accompanied with subsonic loads. The only thing that can be heard from the DeLisle is the firing pin striking the cartridge primer. Take into consideration though that that's a pretty big suppressor on the DeLisle and the gun is chambered in .45 ACP.

Subsonic Ammo Reliability

Since subsonic loads have a lesser powder charge than standard loads they may or may not produce enough pressure to cycle the actions in automatic weapons. The DeLisle is a manually operated bolt action so this doesn't really affect it's reliability. However in say a semi automatic handgun like a Beretta 92 or a 1911 the slide may not blow back all the way to expend the spent casing and load a new cartridge into the action.

Certain modifications can be made to automatics to make them fire subsonic ammo reliably.

Only One Revolver Can Be Effectively Suppressed and it is the M1895 Nagant revolver. The reason a suppressor works with this revolver is because it's the only revolver I know of with a unique "gas seal" action and it fires a gas seal cartridge. When the hammer is cocked or the trigger is pulled on the Nagant, the cylinder rotates and then moves forward into the barrel creating a seal.

All other revolvers have a constant gap between the cylinder and the barrel which allows gases from the fired cartridge to escape through this gap. Putting a suppressor on a non gas seal revolver would actually cause more pressured gas to escape through this gap and would basically make the revolver a lot louder than it would without a suppressor.

Suppressors for Shotguns are very large, not all that popular and require extensive modification to install.


This covers Suppressors.

The Biggest and Baddest

.50 Browning Machine Gun is not the most powerful bullet to be fired out of a man portable firearm. It's NATO designation is 12.7x99mm and is vastly outpowered by rounds like the Russian 14.5x114mm which is used in the PTRD and PTRS-41 anti-tank rifles used in WWII.

Here 12.7x99mm is compared to other anti material rounds including the 14.5x114mm with a 7.92 Mauser off to the far left for scale. Some of these rounds however are used in aircraft mounted guns and anti aircraft battery guns only. Some are obsolete or never saw service.

The Barrett M82/107 is not the world's best sniper rifle. The word "best" should never be applied to weapons in general because oodles of people argue to such a point that nobody can agree on what really is the "best" weapon of it's field.

Anyways I also hear people say the Barrett M82/107 is the most powerful and/or the most accurate sniper rifle in the world quite a lot with absolutely no citation or time put into researching the weapon and understanding how it works. The Barrett M82/107 fires the .50 BMG (12.7x99mm) which as I have stated and proven above is not the biggest baddest round out there and there are rifles that fire bigger nastier rounds like the Gepard AMR and Istiglal IST. It is not the most accurate .50 BMG rifle either.

There are many different bolt action .50 BMG rifles that win in accuracy over the M82/107 because they are bolt action. The M82/107 is not a bolt action it is a semi automatic short recoil operated rifle.

An M82/107 is the rifle credited with the 4th longest confirmed sniper kill, the shot was taken from 2515 yards away, it is succeeded by a McMillan TAC-50 which holds the 3rd and 2nd longest, ranging in at 2,526 and 2,657 yards. The top shot was achieved with an Accuracy International Artic Warfare .338 Lapua rifle, ranging at 2,707 yards.

The .338 Lapua is much smaller than the .50 BMG.

Desert Eagle is not the most powerful handgun in the world and neither is the S&W M500. The legal definition of what a handgun is very unclear but the basic gist of it is it's a firearm with no buttstock and barrel less than 16 inches but the law doesn't seem to mind if you put 17 inch barrels on whatever they originally defined as a "handgun".

In legal technicality this

is considered a handgun. This is a semi automatic "pistol" variant of the FAL .308 battle rifle. .308 that's a full sized rifle round.

From my research this

is the most powerful handgun that I've run across.

Restricted Firearms

Automatics
In 1986 the ATF passed a firearms act that banned all importatation and manufacture of fully automatic weaponry for civilian sale. A fully automatic is a firearm that fires more than one round per trigger pull. What this means is that post-1986 automatic weapons are out of your character's reach unless they're a very wealthy criminal.

The pre-1986 autos still in civilain circulation are very expensive and there's a lot of hoops you have to jump through to get one.

You have to be 21, have no felony record and you have to have a small fortune to afford just the gun and then pay for a $200 tax stamp.

An UZI or a MAC-10 will run up a $3000-$7000 price tag plus the tax stamp.

Explosives

Civilians cannot get ahold of live grenades except smoke grenades. Period. Civilians can own rocket launchers, artillery guns, mortars, tank guns, and grenade launchers given they were produced before 1986 and the buyer goes through the same steps for buying an automatic.

The only explosive ammo they could actually for them would be produced pre-1986 and it has to be registered with local authorities. Take note that live ordnance is extremely rare.

Other Restricted Weapons

The Armsel Striker 12, Armsel Protecta and the Cobray Streetsweeper are restricted weapons and civilians would have to go through the same things as they would an automatic to own one.
