HP Max MK2 tank clamp for Jad's double tank adapter

I am offering a tank clamp for the double tank adapter for the HP Max MK2 from the company Jads.It is possible to change the tanks without having to disassemble the clamp.The screws needed for installation are included in the delivery.By default, there are 3 Picatinny rails on the barrel jacket and one under the tanks; adjustments are possible within a certain range.The total length is 18.1 cm by default, but this can also be adjusted upon agreement.
