Anybody have any experience with this sight?

No, but BSA is really not a good choice.
They suck in general.

Bushnell makes a HOLO site that is good to go.

It's not a Eotech, but it's seems very reliable.

I just tried a BSA panaramic red dot on my S&W 41. It shot loose in 40 rounds. I also bought the multi reticle version, at arm's length the reticle takes up almost the whole window and the top gets distorted. The circle ends up being eggshaped. At much shorter eye relief it was fine but after the problem I had with the red dot I'm sending them both back.

I was using a 42mm BSA tubular red dot with fantastic results. I lent it to a buddy so I'm picking up the 50mm from Natchez for $30.
