Well, after some fighting with them, I got my KAC panels onto my LaRue 7.0...but I was kinda wondering - the way that they popped on, the little metal latch on the rail cover sits in a slot, instead of clinging to a piece of rail. This is the only way it sits flush with the front of the handguard, though I figured that latch would actually grab onto the rail. What's the deal? Is this the way it's supposed to be?
