Vism micro red dot - Vism Micro Red and Blue 1x 25mm Reflex Dot Sight, 3 MOA Dot Size

This review only gets two starts because I had to send it back after it went off while firing and would not come back on. That said, this red dot has many excellent features. The locking base is great and mates with a mounting rail better than my Bushnell TRS 25 Red Dot. The Lithium 123 battery is also excellent, and should give long battery life. Both the Red and Blue Dots are visible in bright sunlight and it was quick and easy to sight in. The lens cover is cheap, mine was cracking right out of the box. If Vism can get their quality control higher, this Red Dot could be a real winner.
