I did explore the Aimpoint magnifier. I didn't care for the field of view (reminded me of looking through a straw) and it just didn't "do it" for me.

In theory the magnifier would be an excellent choice, in reality it's not. Sometimes events can be so dynamic and situations can happen so quickly that you don't have time to fish around in a pouch for a magnifier, locate it, and then put it on the gun. Or if I had the magnifier in a pouch on my SWAT vest and rolled on a bank robbery in progress, active shooter incident, etc and had to deploy the carbine and didn't have a chance to don my SWAT gear then I'm without the magnifier.

I needed something that stayed on the gun and was easy to use. This is the reason you see so many military and law enforcement guys going over to variable powered optics.
