Aimpoint ignorant here, can't take anymore research or I'm never going to buy anything. I need you seasoned AR pros to just tell me what the hell I need to do please.

Option 1: COMPM3
Option 2: COMPM2
Option 3: MICRO T-1 w/ LaRue mount

Either of these choices will exceed my needs, experience level and capabilities but...this is a one-time purchase for the long-haul and I want to get it right (I just need to get something then get to practicing).

Here's my simple requirements (note: I have no easy option to "shoot and compare" so I'll take any help I can get buying "blind");


Use: Primarily target (practice) and will be installed on my home/property defense rifle, 25 to 100 yards would be typical-use but I would like to handle longer ranges on occasion.



Weapon: Stock Colt 6920



I'm not price sensitive but I don't necessarily need the latest-n-greatest either, I just want a rock-solid and simple-to-use Aimpoint. I'm leaning towards the M2, good call? If yes, what mounting system would serve me best?

Thanks in advance.
