Sir, your inquiry has left me a little confused. I don't know if it is a matter of terminology or mission. You say that you want a scope for close range use on a rifle destined for plinking, HD, and SHTF duty, and you shoot at 25 yards ... I am not being critical.
When using a scope, you limit your peripheral vision and end up with tunnel vision, seeing only what is immediately in front of the scope, thereby losing sight of any and all peripheral threats ... not a condition that you want in any form of SD situation. Any degree of magnification reduces your ability to notice peripheral threats.
I think based on the stated mission, that you are seeking a non magnifying reflexive optic, that projects an aiming reference for CQB, but doesn't interfere with your peripheral vision.
I built a CQB M4 type rifle for the fun of it, but I was limited by finances, being on fixed income. I know that higher quality/more expensive options are available, but for starters, I went with what the budget allowed.
I have detachable iron sights for when time allows a precise aimed shot. I have a BSA reflex optic that projects 4 or 5 aiming references on a small tv style screen for fast, close up target acquisition, and a rail mounted laser for intermediate distances. I see the application of this rifle to cover the span from contact distance to 100 yards.
