Machine Guns

A “machine gun” is defined by the NFA as “Any weapon which shoots, is designed to shoot, or can be readily restored to shoot, automatically more than one shot without manual reloading, by a single function of the trigger.” This definition has expanded to include any frame, or receiver of a machine gun, and/or any combination of parts intended to make a machine gun.

A big piece of legislation pertinent to machine guns occurred in 1968 with the Gun Control Act. The Gun Control Act established that imported firearms that had “no sporting purpose” were not able to be sold to civilians. Machine guns as a whole were determined to have no sporting purpose, and thus any MG imported after ’68 are able to be owned only by dealers, military, and police agencies. One bit of good this act did was allowed for a registration amnesty. It became apparent that there were so many unregistered machine guns in the US that had been brought back by veterans, that they should be able to register them tax free. Luckily many of them did, but the amnesty ended after just one month (the feds owe us another few months, this humble author believes).

The last piece of machine gun legislation is to many the coup de grace. In 1986 the Firearm Owners Protection Act was intended to prevent the federal government from creating a registry of gun owners. At the last minute, William Hughes added an amendment that called for the banning of machine guns. Charlie Rangel said that the “amendment in the nature of a substitute, as amended, was agreed to.” However, after the voice vote on the Hughes Amendment, Rangel ignored a plea to take a recorded vote and moved on to Recorded Vote 74 where the Hughes Amendment failed. The bill passed on a motion to recommit. Despite the controversial amendment, the Senate adopted H.R. 4332 as an amendment to the final bill. The bill was subsequently passed and signed on May 19, 1986 by President Ronald Reagan. Thus, Reagan’s signature banned the registration of new machine guns in the USA.

So what does this mean? 

Machine guns are not illegal, but it is illegal to make and register new ones on a form 1 (as you would do for an SBR)

There is no way around the May 19th, 1986 date. if the machine gun in question was made after that date, you may not own it (unless you are a dealer)

Also, there are three types of machine guns that determine the gun’s legal status:

Transferable: Guns registered prior to May 19th, 1986 that are able to be owned by everyone. There are only 182,619 transferable machine guns according to the ATF.

The Federal Laws sound complicated but they are not if you know how to navigate them. We can also help you navigate all the legal aspects of owning any NFA items. 



A silencer or suppressor is defined as any device for silencing, muffling or diminishing the report of a portable firearm. This definition has expanded to include any combination of parts intended for use in assembling or manufacturing a firearm silencer.


Suppressors, also known as silencers, are the hearing protection of the 21st century sportsman. Despite common misconceptions, suppressors are not silent. They are simply mufflers for firearms, which function by trapping the expanding gasses at the muzzle and allowing them to slowly cool.


Suppressors are regulated under the National Firearms Act (NFA) of 1934, which falls under the purview of the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). To legally purchase or possess a suppressor you must:

Be at least 21 years of age to purchase a suppressor from a dealer.
Be at least 18 years of age to purchase a suppressor from an individual on a Form 4 to Form 4 transfer (contingent on state laws).
Be at least 18 years of age to possess a suppressor as a beneficiary of a trust or as a member of a corporation (contingent on state laws).
Be a resident of the United States.
Be legally eligible to purchase a firearm.
Pass a BATFE background check with a typical process time of 8 to 10 months.
Pay a one time $200 Transfer Tax.
Reside in one of the 42 states that currently allows civilian ownership of suppressors.

We sell top quality suppressors from SilencerCo. They are one of the best quality made suppressors on the market today. SilencerCo also has one of the best warranties in the Business.

Short Barreled Rifle and Shotgun

Short-barreled rifle (SBR) is a legal designation in the United States, referring to a shoulder-fired, rifled firearm, made from a rifle, with a barrel length of less than 16 in (41 cm) or overall length of less than 26 in (66 cm). In the United States, an SBR is an item regulated by the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE) as a Title II weapon. In the absence of local laws prohibiting ownership, American civilians may own an SBR provided it is registered with the BATFE, and a $200 tax is paid prior to taking possession of or creating the firearm.

We can help you with any Short Barrel Rife or Shot Barrel Shotgun that you are looking for. We have access to almost any brand you could be looking for. We can also help you navigate all the legal aspects of owning any NFA items.
