Clear solid optic - ADE Advanced Optics RD3-012 Mini Reflex Green Dot Micro Sight

This optic has been mounted on a Bersa TPR9C using a UTG Slim RDM 20 plate. I pressed out the rear sight,installed the plate,and installed the optic with no problems. Directions are well written and easy to follow. The optic was near zero when installed! Sight in went fast. Remember to loosen locking screws before sighting in. My Bersa TPR9C functioned fine with the extra weight of the plate and optic. Ejected brass does not hit the sight. I tested the new set up with 115gr.,124gr.,124gr.+P,138gr.&147gr. ammo. About 200 rounds so far. The Ade rd3-012-G-1 has held zero and works great! This is one of the best buys in pistol mounted optics! I need to buy more ammo.Up date-after 2500 rounds fired still problem free. Very happy. Next up date - round count now 6000-7000, still happy!
