I've used three stocks from Richard's and haven't had a problem with any of them. The one pictured below was ordered for a project much like yours; family heirloom rifle passed down to my son from his great grandfather, stock was too short by almost 2" for him so we ordered a new one. It's one of their Factory Seconds, graded AA by Richard's, less the fill spot and knot which I expected as a Second. I'll guess they graded yours A.
