debating on if i should put the 2.5x on the 10.5 pistol, 1-4 on 15-22, holosun and magnifier on 16in carbine.

opinions? Dont ever see shooting past 200 yrds with any of these.

It's all going to come down to your personal preference. the best we can offer is our own personal preference, so here it goes:

I wouldn't change your arrangement

I also think you nailed it with your original arrangement.  For under 200 yards, I wouldn't change a thing.

If you ever want to shoot longer distances, you could justify a little more magnification (1-6x, 3-9x or similar) for your 16".  Then you can put the 1-4x onto the 5.56 pistol or 15-22.

That sounds like a solid plan imo.  Crossfire glass isn't good for far away, so 22lr is good.  I dig prism sights on short barrels.

The red dots are your easiest-to-use sights with the best battery life... I'd put them on the guns you would protect yourself with.
