Misaligned lens - Primary Arms Classic Gen II Removable Microdot Red Dot Sight

I ordered two of these Primary Arms red dot sights. I tried to zero the sight on an AK pistol. The red dot would shift after each shot. Impossible to zero the sight. I checked the sight afterwards and noticed the front lens was crooked in the body. I checked the other sight and it was the same. I am returning both of them. Optics Planet customer service was very helpful and I received the RMA immediately. I would not recommend this sight. I know the phrase “cheap Chinese junk” is a cliche but it is appropriate in this context.
