I just shot a steel challenge match yesterday with a 16 yr old who is a GM. He used a quick detach mount to take off his optic and turn the same rifle into iron sight so he shot it in both divisions. Sure didn't affect his accuracy. Smoked   us all.

That's kind of what I was looking for. To be able to shoot 2 divisions, same gun, same session. Guess I'll have to test a little to be sure.

They’re RMR footprint so get a scalarworks or LaRue or adm mount that has a great return to zero and you’ll be fine

Hello: The 510C is not a RMR footprint it is the 507C that has a RMR footprint. I have not had any problem removing the 510C and reinstalling it without zeroing it since I put it on in the same spot. That is on a 22 and also my PCC's. Thanks, Eric

Copy you. Thanks for the correction.

The only issue I have ever had with a Holosun is the long Torx screw that tightens the mount onto the rail.  The threads are very soft and will not hold up to aggressive tightening. I found a US made replacement fastener at ACE Hardware and it solves the problem.  As far as returning to zero; mine is mounted on a High Standard Tournament Trophy .22LR using a LSP rail.  As long as it is reinstalled in the same notch and pushed forward it returns to zero fine( at 25m it will return to zero with less than 5/16" variance using Wolf Match Extra) My Holosun is a 4038 which of course has a different footprint/mount.  I have found that the fasteners on anything from China seem to be sub-par and soft.  Apologies if this is slightly off topic.

So just ran an experiment at the range. 5 shots with dot, remove, 5 shots irons, dot remounted in same spot, 5 more shots, repeat... Dot did not lose zero. Feeling confident for this weekend's steel challenge using same gun for pcco and pcci.
