i tossed out the book for it years ago, thinking I would never sell it...but alas.....I am pretty sure its a 8 moa dot. The switch is a dial/knob to turn on and adjust for brightness. This is about an 7-8 year old model cmore and mount if that helps anyone in their decision. Plenty of life left in this mount/sight combo.
Update**looking for lasermax guiderod laser for a glock 24 and a 23** I have a few knives or other BS to trade.
