i don't know about anyone else's experience with hardwood rails but the Skymaster i bought off ebay a couple of yrs ago has hardwood rails. a ys .61 ar was screwed directly to the rails so thoroughly i liked to never got if off. it literally took me 2-3 days to remove the screws. i would twist so hard my hand would lock up. all i could get was a partial turn before i had to let my hand recover. no glue, no epoxy just strong wood i guess.
