Not bad if you can get it on sale - Vortex Golden Eagle 15-60x52mm 30mm Tube Second Focal Plane Rifle Scope

I purchased this scope about 5 months ago and only just recently mounted it. The glass is very clear and it's solidly built. The ECR-1 reticle is perfect for F-Class shooting with only a 1/8 moa dot in the center horizontal an bottom verticle reticle lines that stop short of touching the center dot. At 60x I can literally choose which leg of the "X" on a MR1-FC to place my shot with not mirage. My only complaint is the light transmission at higher magnifications. For example I recently shot a 3x600 yard midday without a cloud in the sky and at 60x it seemed more like an hour before sunset. The image was still crisp, but quite dark.

Had I tried it within the first 30 days I would likely have returned it for a "Night Force Precision Illuminated Benchrest 12-42x56 NP-2DD" and saved $50. That said I really like the advantage of 60x over 42x when conditions allow it despite the poor light transmission.
