Reticle is crooked - Primary Arms SLx MD-25 Rotary Knob 1x25mm Microdot Reflex Sight

So I have two of these and one of them looks great, the reticle is clear and sharp. The other one is fine as well except that the reticle appears noticeably crooked, about 5-10 degrees tilted left (from 12 o’clock toward 11). My rail is level and the mount looks fine, so I think it must be the optic itself. Never had that happen before so hopefully it’s a one-off, but I am disappointed with this one. Normally my experience with Primary Arms products has been top-notch.
