The problem is not the diameter of the turret. It is the separation between the end of the DIN wheel and the LP ports. Either the DIN inlet needs to move closer to the end of the body or the turret needs to extend farther (or longer body).I think Chris mentioned that is why HOG designed the D3 as they did.

The turret is smaller than the body so the Din connection does not interfere with the turret.
