Had a bit of a shock when Ergotron blatantly refused to service their own product and told me to buy a new one. A device of this price should definitely have some kind of a maintenance service!

When my rear sight came loose on my Beretta M9A3 I had a picatinny rail sigh installed. I now got a Holosun HS507C-X2 https://holosun.com/index/product/detail/id/104.html that neatly clears the suppressor.
