Yes, I used xtr2s for years with clipons The 3-15x the 5-25x and thev1.5-8x.
In their day, for sub $1k scopes, i thought they were great and like the reticle and illum at all powers
But the glass is dark, and with say a UTC on a 3-15x side by side with an atacr 4-16x the atacr wins hands down
Atacr also shorter and lighter
if budget is an issue i also had a ziess conquest v4 4-16x and it was GREAT
very clear and had parallax and zero stop.
and sub $1000
But it is SFP and mine was MOA
But those issues didnt bother me with the utc
But i no longer require myself to have sub $1k scopes.
