Hello, my name is Matthew and I'm a Wolverholic.
Ok, so I've conflicting information. Apparently the Wolverine 6M has a floating Md Laser. Older record sheets show it in the left arm, as does the First Succession War book. RS 3039 and RS Succession Wars show it in the right. Which is it? I'm reluctant to go with 'most recent source trumps' since the RS is reprints for a lot of things.
Personal preference in the left arm.
