Put on my new FN SCAR 17S 308 cal. Was almost dead zero at 100 yards after mounting right out of the box. After 8 rounds of sighting it in, put the next 20 rounds all in a 1 inch group at 100 yards. Crystal clear optic and light weight. Would recommend buying any ACOG. Also fastest shipping from Optics Planet of any item I have ever purchased on line.
Pros: Best on the market.
Cons: High price, but you get what you pay for
