Before I would use a CF hand guard may I ask what barrel and stock you are using? Reason I ask is, with a 18" light contour barrel and a alum 12" handguard the Magpul UBR still comes out a little heavy in the butt on a 308 version. I'm looking to lighten up also but I can't really see how to do it without screwing up the balance really bad.
