Considering the expansion of Gorilla Glue I’d think you’d be dealing with some pretty significant cleanup, etc., if you used it. Also IMHO the glue line would be very prevalent. That’s my experience when using it although I’ve never used it on a gunstock.
My nephew used Titebond on his A5 forend that broke in half but it didn’t hold. The last time I hunted with him his repair with black electrician’s tape was still holding
