That second one has quite the holdover for CQC.
I'd hate to be shooting inside 21' for someone's head (because they were behind a loved one or whatever) and shoot over them.
Is it fun to shoot?
The height issue would only be a problem at long distance shots. The gun has a range of 200 meters - but lets face it. With an unmagnified Eotech - 100 yards is about all U'll do decently...... Because of the optic...
I shoot an AK with an Eo Tech mounted on a Ultimak rail out past 200 meters.
