Who makes a handguard with absolutely zero bells and whistles on it? I'm basically looking for the opposite of a quad-rail. I want something as light and ergonomic as possible. I'm not even planning to put any kind of grip on it. I want to use the straight-arm shooting technique that both Mike Pannone and Chris Costa now recommend, among others. You know, just a a smooth tube without any rails on it?
Any suggestions are welcome!
