Shortening a plastic stock
 

I have a Sako 75 finnlite with the stainless fluted barre and the original plastic stock, it has a 14” length of pull. All my other rifles have between 13 1/4 and 13 1/2. I need to either get it cut down or find an after market stock. Can it be cut down?

I can't speak to that gun, but I have a couple of plastic stocked guns and thinking about them, it might be a problem refitting the butt plate/recoil pad.

odds are the stock is hollow inside which limits what amount of material can be removed, so, you would be much better off just buying a stock made correctly from the get go that is the size you want!
there are tons of stock makers out there today,

I detailed how to do this project fairly well last year in another thread:
