One of my thoughts was that you do not have to stay perfectly square behind the red dot like you do a scope. As long as the dot is where you want it you are fine.
Not sure whether that is a good thing for a youngster or not.
I mounted a TRS-25 on my 660 the other night. May play w it some over the weekend.
If that’s your thought, you might reconsider. Even Aimpoints and other higher end red dots that advertise ‘parallax free’, show error. Some may have minimal or none at a set range, but if your eye is not in the same place (good cheek weld), there will be impact shift. At 25-50 yards, it’s often not enough to matter. However, I’ve seen aimpoints shift a foot or more at 2-300. LPVs and Prism sights with a set eye relief and adjustable diopter and fixed parallax setting have proven far more precise, in my use, and every bit as fast.
