Re: Burris 3-12x50 Xtreme Tactical XTR 30mm scope
I bought the olive drab, non-illuminated 3-12x50 XTR about 2-1/2 years ago and had it mounted on my 10FP and then my 5R. The glass was good for the money, and I never had any problems tracking with it. I definitely considered it a good buy.
I ended up selling it off, because I wanted a more dedicatied target-type scope and it funded my McM A4 purchase for the 5R.
Downsides is that they are a bit large and heavy, and the reticle is a bit thick for bullseye seeking (tactical work it would be great). I would get one again except for the fact that the price has gone up a bunch. I think it was a great scope for the $619 that I paid for mine, but now that the non-illuminated is creeping up on $800, I'd rather go with a new Sightron SIII or a slightly used Leupold.
YMMV
