Great optic - Holosun HE509T Reflex Optical Red Dot Sight

The 509T does everything thing you would expect but what your really paying for in this device is the titanium and fully enclosed optic adding durability.

The main reason for writing this review is Holosun excellent customer service. After mounting optic I was messing around with the optic and battery tray I neglected to tighten the side battery tray, then took shooting to zero and noticed the screw was missing and the battery tray. After leaving the range extremely angry with myself I sent an email to Holosun to see if I could purchase another battery tray. I had a reply within 10minutes from Caleb at Holosun. They offered to send tray and screws and no cost not even postage... After sending serial number and purchase info I had the items I requested in a few days. I love companies that take care of customers even when there is no product failure or their fault. This is VIP customer service and an excellent experience. I will be a Holosun customer for years to come!
