I have a short action 300WSM with a removable magazine that I'm considering replacing the stock to one that has a bling mag. This is one of the 300WSM's with a standing ejector.

I think all I need is a magazine box and follower to do this. Can someone confirm that this is correct?

Also, will any S/A magazine box work or is there a special one for the WSM's? If they are the same , I'll rob one from my other actions while I make a parts order. If not, I'll just have to wait......

Thanks for the quick guidance. On my current stock, the woood behind the rear pillar has developed a split (the wood is reallt thin there in the removable magazine version) and I think it's responsible for putting some veritcle in my groups.. I need to get this fixed before elk season so time is short.
