Re: Aimpoint with magnifier
There is definitely a role for a non-magnifed red dot with a magnifier that can flip to the side. It doesn't matter for non-moving targets shooting, but definitely matters for moving targets.
Variable mag scopes have parallax and most even at low mag require the same cheek and eye placement/relief to shoot consistently. When you switch to weak side shooting, awkward positions, shooting from behind barriers, etc...the aiming point shifts with variable mag tube scopes. True 1x red dots excel, since your aiming point does not depend on eye/cheek placement and at what angle you are looking through the scope.
I agree that the magnifier has to be cowitnessed with the red dot and at the appropriate eye relief.
For a CQB to 500 yd semi-auto rifle setup for fast moving Targets and awkward shooting positions, as described above...it's hard to beat a 1x red dot with flip magnifier...or you can consider a Elcan Specter DR.
For bench and prone shooting at longer distances or non-moving targets, go with a variable mag tube scope.
