  • Heavyweight BBs
  • Improved accuracy and stability
  • Compatible with Novritsch ''Full thrust'' platforms

The Novritsch 0.62g Full Thrust BBs are 6.44mm in diameter, which means they are only compatible with snipers that have been upgraded with the Novritsch ''Full thrust'' kit and also require a Novritsch ''Full thrust'' magazine. The higher surface area of the 6.44mm BBs means the force of the BB when it hits is spread over a bigger area. This results in the 0.62g BB causing no more damage than a standard 6mm BB when shot at equal power and range. These white BBs come in a resealable bottle which contains approximately 444rnds, plenty of ammo to hit those shots from across the battlefield and being white means they can be easily tracked due to their contrast with the flourishing colours of an outdoor skirmish field.

The heavier weight of these BBs means they will travel further, provide better accuracy and maintain more stability in the wind. It provides a superior sniping experience and allows you to hit opponents consistently from much longer distances. The BBs come in a practical bottle with a rubber seal inside the cap to protect your BBs from getting dirty or moist.
