Well...since no one else steppd up to the plate...
...there are a lot of factors governing quality of result.
Species of Wood the Stock is made of...Stock's prior finishing history...overall details of the Stock's condition...how old finish is or was removed, or is present...all of which precedes any new Finish, or Stain and Finish.
Probably nothing right out of a can is going to look very good, and for many reasons, among which, is that usually, aside from right preparations, one stains/dyes with intentional materials...maybe then polishing raised Grain, if any is present, then Oils with so-called Drying Oils.
Do you know the Species of Wood the Stock is made of?
Is the old/original finish intact/present?
Is the Wood damaged, dented, scraped, water-rust stained, oil/grease stained/soaked?
