B.R.S.S. Heavy is a new design for fixed stock models, with the new structure the recoil kicks to the shoulder stronger and more reality than regular B.R.S.S. models. B.R.S.S. Heavy has a longer length hammer and longer fixed stock tube, the kick feeling is more direct and up to 30% stronger! This is the strongest recoil system of BOLT AIRSOFT till now!

This new model will first be introduced in May in the Japan area. Soon afterwards this model will also be available in Europe.
