Since the stock has already been refinished into the blond, wouldn't hurt it to use Citri-Strip and then restain it to a more appropriate Brown...
or any other color you like
It ain't that difficult...but I will advise to use a High Quality Stain...as in, Not Minwax...that's the cheap stuff...tends towards blotchyness & color seepage.
Its available in more colors, but it is the low end and gives one a lower-end stain as compared to higher quality stains...
Formby's, Old Dad's, General Finishes, Wood You brand, etc...get the good stuff, it ends up with richer color & depth
Now their Polyurethanes I like...and use their Marine Grade poly (Helmsman Spar) for hard-use hunting Gunstocks quite often...
and the Crystal Clear for showpiece stocks...
But having done much furniture & gunstock finishing & refinishing...Minwax Stains just suck, IMHO
