I have used CASCOPHEN Resorcinol (2-part marine grade glue made by Humbrol) for about 30 years with excellent results.

Do NOT use Cascamite or similar! totally different stuff

parts need to be clamped for 24 hours

also: Cascophen has a dark brown colour which is very near most gun stock colours.

Not sure whether this is available in the US, but nowadays should be obtainable through the internet.
