Was shooting groups at 880y today with my prs rig, runs a minox zp5 5-25x56, arguably some the best glass on the market. Also shooting a load development ladder with my new 22" supressed 6.5saum, it's topped with this new vortex. Conditions were prime, 75° light cloud cover, 2mph breeze. The glass is not minox quality nor did I expect it at half the price. But it held its own! With parallax at 600-infinity there was no parallax in the scope at 18x. Glass very clear and bright reticle is not a hindrance. However I spend the majority of the time behind tree reticle scopes. I really like this scope thus far.
