I'm with most on this topic. Get rid of the See-Thru's.Like mentioned they raise the scope to high. The S-T's are made of Aluminum Extrusions.The slightest bump will knock your scope out.If they were made of steel they would probably be a good idea. I've never seen steel See-Thru's telling me nobody makes them.Buy a good set of rings and bases and trash the See-Thru's is my best advice.I have a gunsmith friend who has a wall full of them,ones taking off of customers guns.That proves something to me.
