Recently looking at the Carbon C4 "Mr Dark" it would be interesting to see if an analogue could be made based on the Seac Sub "Shotgun". If a bulbous air tank could be grafted into the lower rear section of the gun to provide the same belly shape this would make an interesting gun in terms of tracking while mainting a more normal compression ratio, but how to do it? Some time back we saw a gun with an air tank in a rectangular block under the rear of the gun which itself was narrow, but nothing more was heard of it. From memory the name started with an “S”.
