I recently purchased an IBM M1icon carbine from CMPicon and am hoping if someone could answer a couple of noobie questions.

What would be the appropriate type of stock and would this carbine have been originally fitted with a flat or round bolt?

The carbine receiver sn# is IBM 3665XX and the barrel is marked IBM 3-43.

Thanks very much for replies. (some of you must get really tired of answering the same questions, but this beginner really appreciates your knowledge and help!) BTW, it's a nice shooter!
