50 BMG
The 12.7x99mm/Caliber .50 cartridge used in rifles such as the Barret M82, MacMillan Tac-50, and others, as well as in the M2 machine gun is known as the .50 BMG - not the weapons themselves. BMG stands for "Browning Machine Gun", as the cartridge was developed for the Browning M2 machine gun.
You will have to contact the company
If you mean the .50 BMG (there ARE other .50 caliber cartridges) it is a restricted firearm, requires licensing. There was a move to ban further imports of .50 cal BMG AMMO and rifles, but do not know where that stands.
Without more information, the price range could be from 50-5000 USD.
