The Vortex PST Gen II 1-6 x 24 is a great fit for the AR platform. The clarity is crisp and impressive from the lowest magnification to the highest. The glass is bright with easy target acquisition. This scope has the perfect combination of magnification and size for most uses of the AR. The scope itself is on the heavy side but not enough to dislike it on this rifle. The lighted reticle with adjustable intensity is great in low light and direct sun. All the adjustment knobs are sturdy and stay where they are put. I am very pleased with this scope. I own other Vortex products and will continue to buy more as Vortex has amazing customer service and a VIP warranty.
