Description
12.7 x 108 mm Cartridges
Atlas International Group deliver and supply 12.7 x 108 mm cartridges. The 12.7 x 108 mm cartridge is a heavy machine gun and anti-material rifle cartridge and takes on a similar role to the NATO .50 BMG (12.7x99mm NATO) cartridge. While the two differ slightly in shape, weight and size, the larger 12.7 x 108 mm round gives it more capacity to hold different types of powder, and can even be used on a variety of different targets such as unarmored vehicles, penetration of lightly armored vehicles and also destroy external ancillary equipment on larger targets.
Although the US .50 BMG NATO cartridges serve a similar purpose to the 12.7 x 108 mm, interchangeability is not supported. Due to dimensional differences, the cartridges cannot be chambered in firearms that are designed for the other, so please take care when purchasing that the firearm you possess is intended for 12.7 x 108 mm.
