Great scope for the money - SIG SAUER Tango-MSR 2-12x40mm Rifle Scope, 34mm Tube, First Focal Plane

I recently purchased a the Tango MSR in a lower power, loved it. Then bought this big bad boy for my AR10. Stays on target, easy to adjust for drop, windage, etc. Big, huge primary lens for looking into the night. The only drawback is the eye relief is touchy: your eye is slightly too far back or too close it's like looking down a pipe. All scopes do this, this on is just a little touchy, easily overcome with a good set-up.
