forgot in my last post. quality rings and bases with proper mounting are more important then putting all your beans into glass. this year alone ive mounted 10 times more then most do in a lifetime so trust me when i say this, scopes bugger up every now and then but rings and especially fasteners go wrong all the time. go to anywhere that offers professional scope mounting and talk about old rings going bad. thats also another thing most guys dont know, most rings NEED replacing every decade or so. maybe not the entrire ring set but the fasteners for sure
