Just got the same Aimpoint for my LE6920 - zeroed it last weekend and so far I love it! That being said - it's the first optic I've used so my opinion matters very little in the grand scheme of things but throwing in my two cents regardless 

I Use a Aimpoint patrol rifle optic on my Ruger SR. 762 for shorter ranges and and a Nikon Prostaff 4x12 if I want to reach out a ways. Perhaps a bit of overkill for a 22 but I just love good scopes.
