About a year ago I was looking for an MC Operator and couldn't find one anywhere. Now there seems to be quite a few on GB, and probably other sources. Are they made in batches is that why the supply ebbs and flows? I'm hoping to get one in the next few months, and REALLY hoping there are some around then. As far as construction, what is different about it then say a Loaded? Obviously the rail, but what is different in the construction and materials? If someone could answer or point me in the right direction, I would appreciate it.
