This is the new Primary Arms / Holosun dot. They are now out of stock at primary arms. 50k battery life. Awesome little site but I can't get used to the chevron so I want to buy the model that is only the single dot. Has 2 scuff marks. 1 from from where my buddy brushed his rifle up against it when it was sitting on the table and another on one of the turret caps from when I dropped it and kicked it across the driveway. Comes with everything from the factory minus the allen wrench which I promptly lost 17 seconds after taking it out of the box. 200.00 shipped.
