Guns are 14th century technology.
Anyone with moderate intelligence and 14th century intelligence can make a gun.
So long as guns are not registered, guns can be bought or sold privately.
Even if they are registered, they can still be stolen and manufactured.
Yes its really easy to buy a gun from a private sale. If you don’t want a background check you don’t need to do it.
The only reason I did it was to get a specific gun (Keltec PMR 30) that I had no chance to acquire through a private sale.
I believe the 14th century is also when gun grabbers first appeared.
Wherever there is freedom and liberty, there will be a Leftist wanting to take them away.
