Best polymer sights for the money - FAB Defense Top Mounted Deployable Front Sight

These come in at a great value in my opinion. I was a little hesitant at first because there is no manual locking mechanism for the sight in the upward/downward position, meaning I'd like to have to push a button to fold them up/down, but my worries were eliminated once I felt how solid the lockup was. These detent nice and firm in the up and down positions. These sights are also easy to adjust. As a bonus, the aesthetics happened to match my Sig Romeo5 red dot perfectly and they co-witness like they were meant to be used together. I ordered this separately from the rear sight which was cheaper than buying them as a set.
