A buddy just spent over $400 for an aimpoint comp series sight. I saw this Vortex and did a little research on their website. I couldn't find many reviews about them but with their (leopoldtype)warranty it was worth a shot. I copied this off of their website. Repair or replace your Vortex product for any reason at NO CHARGE TO YOU. It doesn't matter how it happened, whose fault it was, or where you purchased it. The manufacturer reports the sight is paralex free at 50yds. The slight paralex seen from moving your eye around is minute. If your looking for a CQB sight try this before you spend the $400-600 for an aimpoint, or EOtech. I mounted it on my RockRiver AR-15 flattop.
Pros: price, features, 2x multiplyer included
Cons: multiplyer must be screwed on, alluminum mount
