A machine gun is a fully automatic mounted or portable firearm designed to fire bullets in rapid succession from an ammunition belt or magazine. Not all fully automatic firearms are machine guns. Submachine guns, rifles, assault rifles, battle rifles, shotguns, pistols or cannons may be capable of fully automatic fire, but are not designed for sustained fire. As a class of military rapid-fire guns, machine guns are fully automatic weapons designed to be used as support weapons and generally used when attached to a mount- or fired from the ground on a bipod or tripod. Many machine guns also use belt feeding and open bolt operation, features not normally found on rifles.
In the U.S.A, a "machine gun" is a legal term for any weapon able to fire more than one shot per function of the trigger regardless of caliber, the receiver of any such weapon, any weapon convertible to such a state using normal tools, or any component or part that will modify an existing firearm such that it functions as a "machine gun" such as a drop-in auto sear. Civilian possession of such weapons is not prohibited by any Federal law and not illegal in many states, but they must be registered as Title II weapons under the National Firearms Act and have a tax stamp paid. The Hughes Amendment to the Firearm Owners Protection Act of 1986 banned new production of firearms classified as machine guns for most civilian applications, however, so only "grandfathered" weapons produced before this date are legally transferable.

    An odd one for sure. Pretty neat history, so just passing it along.

    If the Hughes Amendment ceased to exist, what would you Form 1 MG-wise?

    Let's pretend for a moment that the Hughes Amendment is repealed or declared unconstitutional (shaaa ... it could happen). What would you stamp/convert and why? Enjoy!

    Machine-gun, Oregon Bureaucratic Bullplop, etc.

    I am seriously considering investing in a machine-gun that a member here has for sale. I've got the greenlight from my better half and now that the tax BS is done for this year, I'm more solid on the funding aspect. That said, one thing that concerns me is the absolute blizzard of gun control...

    American's First LMG (M1909 Benet Mercie)

    The video is neat overview of the weird, early M1909 LMG. Ian didn't mention it, but Hiram Percy Maxim created an early silencer for them.
