Haven't seen the particular mounts you are talking about, but typically all the see thru mounts are rather hoaky. Very easy to knock out of whack. The problem is the thickness ( or thinness) of the metal arount the see thru hole. I'm prejudice but good rings and an elevated base are the way to go. I've seen several folks get their rifle bumped or dropped and that puts them out of the match for that day. Don
