Sliding block or interrupted screw for an autoloader?

Would an interrupted-screw breech make an autoloader harder to build than a sliding breech?

Both have tradeoffs. An interrupted screw would probably be preferable in a turret with more than two guns.

A viewer asks whether a Welin-style interrupted screw made automation harder than a sliding breech. Both arrangements have advantages and disadvantages, so there is no universal answer. An interrupted screw would probably be preferable once a turret carries more than two guns. A sliding arrangement remains understandable because the surrounding turret geometry and gun count shape the choice.
