Wow these are now my favorite sights - Aero Precision Aero Flip Up Sight Set - Gen 2

These are simply amazing. The sight picture, feel, coating, and operation are great. My one criticism is I wish that once in the fully upright position they would lock into place, however, the spring tension that holds them up is strong and I haven't had them fold down on me during hard use. I have tried to get it to collapse and stay down by intentionally dropping it on them at various angles and I haven't been able to make it fold down without putting them back down by hand. I'm in love with these. I will be buying more. My favorite thing about them is the sight picture, which is perfect!
