Mixed bag, but I gotta provide some props for a company doing me right.
I bought a Daniel Defense micro mount for the Aimpoint on an AR pistol.
https://danieldefense.com/micro-mount-rock-lockr.html Picked it up from Optics Planet, everything arrived in a timely manner, great price, etc. Unfortunately, by the time I got it mounted up and got it to the range, I was outside the OP return window. Had a severe problem with windage, too much to correct with the Aimpoint's built-in adjustments. When I started looking into it, I discovered that the mount did not fit the Aimpoint properly. Rather than wedging into a zero-clearance fit, it could be rotated noticeably when the screws were loosened. So there was basically no way to ensure the Aimpoint was pointed in the same direction as the barrel when installing it.
I reached out to Daniel Defense and they offered to take it back and refund the purchase price if they agreed that it was defective, even though I didn't buy it direct. I sent it back. Took several months, but eventually, a check did arrive.
Pretty nice to not get scrood. So I can't really recommend that product, but I do appreciate the company standing behind it.
