I'm looking at the Yankee hill manufacturing diamond rail but have some questions. I've never free floated a barrel, so what do y'all prefer? Mid length or rifle length? I have a 16" barrel. Does the rifle length weigh significantly more than the mid length or is it negligible in the grand scheme of things? To be honest I'm leaning towards the rifle length, since I think it would look better. But I would like to see y'all's thoughts on this before I go out and buy something. Thanks!
