Well, it is the same size length wise as an M2, It has the cuts that "APPEAR" to be genuine and aged as compared to the rest of the finish. I did not take this off of a rifle, I purchased around a thousand stocks and this was in the batch. It just threw me off because of the cuts, and was wondering if any known MK I Rifle stocks were cut down or if this one is just a "Sportarized" version. Thank you for your replies.
