Got a 5x today... Already packed it up and shipped it back to optics planet... Great in theory, but not so much in practice. Was very unimpressed with it.
Apparently many of the mounts are crooked on the X-Sights. one of the UK guys posted over on THF with a picture. The holes in the scope appear to be off center. I checked mine, slightly off center. This is poor machining, I'm guessing most of them are not straight. Look from the bottom to see if yours are straight.
The only reason I did not is I wanted to record my hunts, am almost over that too...I* still think the 5x and 4.x to start with are too close a 3x is much better for FOV
