Sheesh! never ask any political anybody or group about firearms to start with.
A BMG 50 is a .50 caliber Browning Machine(full auto) Gun, this means that it will continue to fire rounds until it has expended the supply of rounds in the gun.
To legally own a Machine gun one must have a Class III FFL.
There are other versions of this firearm that are not full auto but semi-auto and single shot. Most are used for competition and just general "fun" shooting when you can afford the ammo.
IMO this is the perfect homeland Militia heavy weapon.
That survey needs to be researched to find it's origin, You'll probably find it is linked to the anti-gun movement.
glock You have anything to add to this?
You can buy machineguns from a class 3 FFL but you don't have to be a FFL to own a machinegun. Paperwork and a $200.00 transfer tax is all it takes in most states.
The old "Mix up the ammo to the gun" argument.
.45 Auto Revolver
.22 Long Rifle Pistol.
Shall I go on? I'm having a little fun with this.
