300mm VSR Barrel

The TNT barrels are a unique barrel with some awesome qualities, they are 6.03mm for most of the barrels length, with the last portion expanding out to 6.35mm with channels cut into it. This design is to ensure that the BB leaves the barrel surrounded by a cushion of air and centralised to the barrels bore, this helps increase the consistency in the BB's exit and enable a flatter flight path for longer.
