Build quality lacking - Crimson Trace CTS-1550 1x 3 MOA Reflex Red Dot Sight

After roughly 300 rounds on a .22 pistol, the red dot lost its zero. When trying to re-zero the dot, the windage and elevation adjustments were not working properly; adjustments did not move the dot far enough down or to the right. Upon closer inspection, I observed that the emitter came lose from its housing which is why the adjustments were not working. I contacted Crimson Trace and they stated that they would send me a replacement once the CTS-1550 was back in stock. Six months later at the time of this review and CT claims that the CTS-1550 is still not in stock.
