The magazine is inserted backwards.

Shells are taper with a wider base than shoulder where the case and the projectile come together. Cases are tapered for two reasons, one this makes loading the shell slightly easier like water through a funnel. Secondly, this makes case extraction, especially from a dirty or heated weapon, much easier. The tapered case breaks free easily on all sides and any brass shaving do not get caught and drag.

This is the reason for the "banana" shape of military magazines like the Bren gun or AK-47. Each magazine holds cartridges with a aggressive taper and rimmed case. The magazine for the M16 series is less so, but a curve is still present as the cases are semi rimmed.

The magazine was intentionally curved backwards so that it would not collide against the shoulder armor when the gun angle is depressed, pivoting at the elbow joint. If it were curved in the usual direction, it be butting against the shoulder. Coulda done a vertical mag, but again, this allows for greater range of movement. This is a British vehicle, remember. Sometimes they relish doing things ass-backwards. ;)

I could see that in the picture.

However, imagine the ammunition for that magazine................ Wide throat, tapering to a narrow base........... exactly the opposite of what you want in reliable ammunition. If it went into the side (FG-42) that would make more sense, after all a magazine is intended to be replaced. The pilot couldn't reload in this configuration now and would need another mecha and pilot to do that operation for him.

I guess that side loading is the way to go.

Thanks, Thomas! Another one winding up more or less just how I wanted it. Except for maybe side view of shoulders, but almost never happy w/ that spot on any mech. :P

I think the side view is okay. Only thing I could image would be something like hooks with rings added, to break up the plane, but that'd destry the nice front look. Otherwise you could add some small 'mudplates' liek on the front of the tank, and give a small bump (as on the storage boxes of the cruiser) for some subtle form. Dunno.

Those are good thoughts. For Practicality, all arms should probably have loops or rings so they can be easily removed or added.

Did some work on Siegfried last night. Will show you something soon.
