Just a word of caution - I recently had an issue with my MTC Viper - not the Connect. Basically the turret zero sleeve locked up hard on my top turret. Had to get forceful with it and scuffed it up. I thought no issue contact MTC and ask for a replacement turret to get it back to mint - No can do they said they are not removable and they couldn't help as made overseas and assembled there etc.
So it may not be as easy as a quick tighten up!
Re the rubber eye bit - I would not think it an issue mid comp as the rules are re parallax. The issue may be somebody thinking you were doing something untoward! But there are a lot more experienced HFT guys on here that will confirm or otherwise!
