Gunsmithing Steyr SBS and the McMillan SBS stock?

[Muskox]

Anyone ever install one?

I have 3 Steyr SBS rifles, and I am thinking about getting one for all 3.

Does the magazine system require any parts change over?

I am doing a 450 Marlin, two 308s.

I'd call and talk to McMillan but I am in Australia.
