When I purchased my AR it came with flip-up sights. They were wobbly, and not at all repeatable for zero. These sights are SOLID, hold their zero, and are just like the original sights on the M16-A2 I used to shoot in the military. Very high quality manufacturing - great finish and smooth operation. If you want top quality, don't settle for anything less.
Pros: Sturdy, solid, repeatable, professional
