Since this is an election cycle, lots of firearms terms are being thrown around that neither side really understands. In the area of firearms, there are a large number of terms, phrases, and acronyms that need to be fully understood in every conversation.

The first of these, seen almost daily in the media, is “automatic,” as in “XXX owned an arsenal of automatic weapons!” (usually in 3 inch headlines). To the general public, this suggests that some type of machinegun was present – a nice scary term to sell more newspapers. But we, the gun owners, have used this shorthand for over 100 years.

To define the terms, an “Automatic” in common usage is a Semi-Automatic – so what’s the difference? A Semi-automatic, also known as a self-loading pistol, shotgun, or rifle, fires, extracts and ejects the empty case, cocks the firing mechanism, and loads and chambers the next round. Then the action stops, until the trigger is released and pressed again.

A media “arsenal” of ”automatics” – and not a machinegun in the bunch! But the camo background adds a nice scary touch.

A Fully Automatic, aka a machinegun, Title II gun, or Class 3 gun, does all of the above, BUT also releases the firing mechanism to fire the next shot, and will continue to do so until you release the trigger or run out of ammo. These are rare, very valuable, and, to the surprise of many, completely legal in most states. There are about 160,000 legally owned machineguns in private hands in the United States – and they are the guns least likely to be used in a crime. In fact every owner of a machinegun has had to submit fingerprints and a photograph, and undergone a background check in order to obtain their gun(s). We will go through the purchase process after we cover some other items.

Semi Or Full Auto?

How can anyone tell if the firearm they are considering buying is a semi or full auto? It’s fairly simple, and known by the Alcohol, Tobacco, Firearms and Explosives employees as “Field Test #1.” Here are the steps:

  1. Unload the firearm – check it twice.
  2. Function the action (pull back & release the bolt or slide).
  3. Pull the trigger and continue to hold it back – you should have heard a click (the firing pin going forward).
  4. While holding the trigger back, function the firearm again.
  5. Release, and then pull the trigger.
  6. If there is another click, the firearms is likely a semi-auto.
  7. If there is no click, the firearm is likely a full auto

That is all there is to it. The test is not definitive, as the gun could simply have a broken part in it, or be so far out of adjustment that it allowed the firing pin to fall as the action closed, known as “following,” as the firing pin or hammer “followed” the bolt closed.

Why do you need to know this test? Because lots of machineguns have been “cloned” as semi-autos – even belt fed guns.  I have seen ads for semi-auto Browning Automatic Rifles (BARs), WWII style M1919A4 and A6 belt fed guns, and many more. Plus we are all familiar with the AR15 clones of M16’s, and semi auto AK47’s.

Are these machineguns, or not? Field test #1 can tell, but these all have semi-auto clones out there. (These are real, registered machineguns – a 1919A4 belt fed, a Thompson M1928, and an MP5).

Along with machineguns, and covered under the same laws, are Short Barrel Rifles (SBR) and Short Barreled Shotguns (SBS), sometimes called “sawed off” for dramatic effect. The Federal laws define a SBR as a firearm with a rifled barrel shorter than 16 inches, and/or an overall length of less than 24 inches. A short barreled shotgun has a smooth bore barrel less than 18 inches, or an overall length of less than 24 inches. [Why the different lengths for rifle & shotgun barrels? No one seems to know, but that’s the law!] Once again, how do you measure them? It’s still easy.

For Barrel Length:

  1. Unload the firearm.
  2. Remove any detachable muzzle devices – flash suppressors or muzzle breaks.
  3. Close the action.
  4. Slide a rod down the barrel until it stops against the closed bolt.
  5. Mark the rod where it exit’s the barrel.
  6. Remove the rod, and measure from the end that was against the bolt to the mark.

For Overall Length:

  1. Unload the firearm.
  2. Go to a vertical corner, where 2 walls join the floor.
  3. Place the barrel of the firearm vertically in the joint where the two walls meet.
  4. Lower the firearm until the rearmost portion of the stock rests on the floor.
  5. Mark the end of the barrel on the wall.
  6. Measure from the floor to the mark.

(It is done this way because some small firearms have curved rear stocks, to be held in one hand while the other is on the forend.)

Other Title II Weapons

Supressors

“Silencer” – sounds sinister, doesn’t it? But the real name is suppressor, as these devices only reduce or ‘suppress’ the sound of a shot – only in the movies are they silent. They were invented by Hiram Maxim’s son, who also designed “suppressors” for cars – we call them mufflers. (Maxim Sr. developed the first functional machinegun). Federally, they are defined as “any device that reduces the sound of a shot.” I know of one case where someone built a stand, and placed a 30 gallon drum on its side in the stand. He then filled the inside of the drum with insulation, with the intention of shooting through it with his rifles so as not to disturb others. ATF (now ATFE) found the device and made him destroy it or face Federal criminal prosecution. So they do NOT have to be attached to the gun to be a suppressor. And yes, taping an empty plastic soda bottle to the end of your .22 makes it a suppressor, and you’re a felon! (Plus they are not very effective).

Suppressors are the fastest growing part of this community, as several states have made them legal for hunting. As more folks (like us) have moved into the “Urban Wildland Interface” as firefighters call it, some have objected to hunting with firearms, thus reducing the available area to hunt. Suppressors allow hunting closer to these homes – but be aware of the law in your state. In Arizona, it is illegal to hunt within ¼ mile of a dwelling without the resident’s permission. And in almost all cases, you still need to wear hearing protection.

AOWs

The next category is Any Other Weapon – AOW. This is basically anything that is a gun, but does not look like a gun. Cane guns, pen guns, the very, very rare Nazi belt buckle gun, these are all AOW’s. They go through the same process as the others for purchase, but the fee is only $5.

Destructive Devices

Lastly are Destructive Devices – anything that explodes and any firearm that uses fixed ammunition larger than ½ inch in bore size. In this category there are the “regular” explosives – dynamite, C4, etc. Also, just added to the list are the “binary” explosives like Tannerite. The components are OK if they are separate, but once they are mixed, ATFE says if you move them, you need all the permits as for any other explosive.

I have met folks who own such things as a 20mm Swedish recoil-less rifle, a French 35mm anti-tank gun, even a 3” Naval cannon, mounted on a flatbed truck. With the proper papers, they are all legal – and impressive!
