I am not a fan of superglue for repairing stock cracks... It is strong but not very shock resistant.

I drill a tiny hole at the end of the crack and heat the wood thoroughly. Apply a small bead of slow-curing epoxy along the crack including the bare wood on the inletting and cover with saran wrap. The cooling wood will create a vacuum and suck the epoxy in deep.

Clean-up is easy with a sharp knife.
