How big of an issue is it if the barrel ramps are ever so slightly proud of the receiver ramps? The barrel is clocked correctly, the ramps line up perfectly, but there is a visible and tactile ledge where the receiver ramps meet the barrel ramps. All chambered rounds seem to make contact 3/4 of the way up on the barrel ramps, so my thought is it may be a non issue. My question is, should I seek to get this fixed or leave it be? This is a new, factory, complete upper receiver group.
