The reload is largely faster because you don't have to swing a very large portion of the weapon (Remember, it's also a flail, and machine guns aren't light on the front end as is) back up after reloading, then lock it in place with something resilient enough to resist afforementioned heavy front end swinging around in melee combat.

Resilience is also going to be highly valued given that it'll be used to block blows, the possibility of a retracted "Mace" form, using the haft as a secondary weapon when swinging the whole weapon isn't an option etc etc.

While an internal clip does have it's advantages, in this particular case, imho, the disadvantages outweigh them.
