Those see-thru mounts are by far the cheapest, flimsiest mounts one can put on a rifle. I honestly see no reason to put any sort of removable or see-thru scope mounts on a deer/bear rifle. One will have more accuracy with a scope in just about any situation. I can't see iron sights benefiting anyone other than a very experienced rifleman, and a rifleman with experience would probably do just as well or better with a scope also, so again I can't see much benefit in iron sights for anyone.
Well, I can see no better way to train a new rifleman in the good hand-eye coordination necessary to properly use iron sights. In fact, I think that scopes are best suited for experienced riflemen who already know how to use iron sights.
In the Marine Corps we were trained to shoot at human sillouette targets at 500 meter (about 550 yards) with iron sights on our M-16A2's. I averaged about 7 out of 10 in the black at the 500 meter line. It's actually not that hard once you understand what's you're doing. After shooting at 500 yards with iron sights, a 200 yard shot with a scope from a steady position is child's play.
