I've got a no3 223cal with a forend without barrelband. It is a little wider than the regular forend, with the sling swivel screwed into it....I've been fooling with No 1's for a long time, but never paid much attention to No3's, so I need a little help. Is this factory or a replacement? I like the rifle, shoots good, easy to tote, just want to know more about it.. Thank y'all for any help..
