Folks, I am just providing some information. I have an older ATR in 308, with an internal mag. It is fluted and the wood stock has seen better days. I couldn't find any affordable options, so I called Mossberg. The folks there were great, and about $75 later, a new black synthetic stock shows up promptly at the door. Works great, is free floating, costs is great. Thank again to Mossberg for helping out!
