Not reliable - Trijicon ACOG Mount RMR Adjustable Red Dot Sight w/ MOA Dot Reticle

Goes out randomly when shooting or even racking the slide. Comes back on randomly or does not and you have to power the unit back up but again it will go out. Also the auto adjust feature works poorly. Not recommended for home defense. If you are in a dark room and are moving to a lighted area the unit will not always adjust the red dot until you are completely in the lighted area making aiming with it during the transition difficult if not impossible. I had the RM02 and exchanged it for this one because of that. Now this one is defective. I regret buying it.
Pros: None - not reliable. Suitable for target shooting only.
Cons: 2 units so far, both with issues.
