Re: Burris 3-12x50 tactical.. Any good?
I've seen new one's sell for around $670. Used one's are in the $500-$550. range.
As far a quality goes, the Burris Extreme Tactical, is a poor man's Leupold. Except it has none of Leupold's virtues, and all of Leupold's vices.
In short, it's a Tactical scope that has: MIL/MOA, SFP, large undistinguished plain MILDot reticle, rotating eyepiece when you change zoom power (very annoying if you use BC Covers), and it's a rather large and heavy scope.
In short, for about same money, you could buy a new ($679 from Liberty Optics) Bushnell 4200 3-12x44mm Tactical, and get FFP, MIL/MIL adjustments and Illumination.
Or for $599. you could buy an SWFA SS 3-9x42mm FFP MIL/MIL. Don't let 9x power deter you. Whatever you can do with 12x, you could also do with 9x.
Both the Bushnell and the Super Sniper are miles ahead of anything Burris offers the tactical market.
YMMV,
