I don't recommend see-thru mounts. The ones I have had experience with (used to work in a gun shop-I know this doesn't prove anything, but I saw alot of scopes mounted in such contraptions)had a couple of serious disadvantages:

1. Put the scope up too high for optimum use of a scope vs the combof the stock.
2. Were relatively weak-easy to knock out of zero when hunting. (Except for perhaps some of the German ones, which are build like a bank vault, not made of thin aluminum!!)

In the U.S., we regard a scope, when one is on the gun, as the primary sighting system. When mounted and used correctly, a scope is the fastest and most accurate form of rifle sight. IF you are encountering problems usinga scope at short range, you need to practice acquiring short-range targets with it.

A scope should be mounted so that you can close your eyes, mount the rifle to your shoulder, and be looking at the full field of view of your scopewhen you open your eyes.Then when you start practicing on short-range or moving targets, KEEP BOTH EYES OPEN UNTIL YOU PICK UP THE TARGET. This will keep you from "hunting around" with the scope trying to find the target!

With a properly mounted (low!!) scope, and keeping both eyes open, I have no trouble easily acquiring targets as small and mobile as a goldfinchin wooded terrain with a 6X scope at rangesfrom 25 to 100 yards.I have practiced this skill for many years.As you may have noticed, I just don't like, trust, or recommend "see-thru" mounts to a serious hunter!! But to begin with, you might find 2.5X or 4X a better magnification to use for practicing. Many people insist on using scopes at a magnification setting much higher than necessary for good shooting!
