The 3Tactix PRD3 is advertised as Riton’s every day cary micro red dot but has features that are far from ordinary. It offers 3 user selectable reticles: a 2MOA dot, a 50MOA circle-cross, and a combined circle-cross and dot. It has motion activation with a 50,000hr battery life. And a pull-out side battery tray. The PRD3 somehow manages to offer all of these features with a low-profile design which has a lower base than most side-tray battery red dots by its competitors.
I tested PRD3 on an RMR cut slide but found that the PRD3 still wasn’t low profile enough for me to use Glock factory iron sights. For testing, I mounted to my Glock via an MOS/RMR adapter plate. The PRD3 is the RMR footprint model of the 3Tactix red dot line and comes with a RMR to Picatinny 1913 adapter.
