I got one (well 2) of a bad batch a dealer got in early 2019 (gray/black version but not first really long overall length, so I think gen 2). Overall I liked it, but right out of the box the elevation turret had issues, you could only lock the turret back down if you rotated between clicks while pressing down, windage was fine. Dealer was happy to replace it. The second one had the same issue and when I was running the elevation/windage through it's range the elevation started grinding and locked up in the middle on about the 4th trip. Dealer was going to replace it a third time, but they noticed all of the ones they got had the same issue with the elevation knob only locking between clicks, so they just refunded me and were going to deal with Sig.
That aside it seemed like a nice optic, no where near worth Sig's ridiculous MSRP of like $2800 at the time, but everyone was blowing them out for around $1200 pretty consistently.
