G&P Gas Charging Collapsible Stock Set for Tokyo Marui M870

Ever felt as if you wanted a Collapsible Stock on your Tokyo Marui M870 rather than its own stock? If you do want it changed, you'll have to rework the Gas Charging system as well. G&P have answered both these points with their Gas Charging Collapsible Stock Set which also comes with a very ergonomic pistol grip set so you can alter the size of the grips for your comfort.
