I got a James River Armory "standard" coming. By" Standard" I mean 22'' GI walnut with metal butt plate and flash suppressor . I am not sure any of the terms are correct lingo. I am looking to scope it but don't want a Scout setup. I looked at "CAnaidianScopeMount CASM . Any drawbacks that I can't see to it? Anything else needed to make it shoot to it's potential?
