It's a semi-auto shotgun that uses a tube magazine.

The "mechanical shell" is a...well...mechancial shell that covers the tube magazine. When it folds out it acts as an emitter for the energy shield.

And the reason I went for energy shield was because I couldn't think of a good way of describing the folding out bits turning into a shield that yall would accept, but I guess apparently coming up with a succinct way of describing folding out bits emtting an energy shield wasn't good enough either.
