That rifle has a 15 second polyurethane (or some other thane) sprayed on finish. No oil is going to penetrate the plastic finish.
If you do strip it to bare wood, BLO is not your friend even if it looks good early on.
Everyone has their pet finish and mine is pure tung oil.
You do realize "pure tung oil" does not have to have any tung oil in it, right?
Tung, in service, is virtually identical to linseed oil and used interchangeably. Lots of people are allergic to tung nuts so it is not used as food. That means it all goes into paint and chemicals while the best linseed oil goes into food...
