I personally wouldn't have "See Thru" on any rifle I own.They raise the scope to high plus they are made of Aluminum Extrusion. The slightest bump will knock them out of whack.I had a gunsmith buddy back home. He had a wall full of them hanging upfrom customers guns he took them off of.It might be different if they were made of steel but I have never seen any other then the Aluminum extrusion ones. Years ago they made a "Swing Over" set up.I can't remember who was making them or actually what they were called.The rings were attached to a base and basically ithad a swing joint that you would roll the scope overto the side.That let you use the the iron sights.I'm sure some of the old timers would remember these. I haven't seen them in several years. Those were pretty decent as long as you made surethe rings were all the way down,snapped on the base before taking your shot.
