Looking for a red dot with low rise mount for Sig Bravo 4 Scope

[Rattler5]

I have a Sig Bravo 4 and am looking for suggestions for a red dot (preferably with a 2-3 MOA dot) sight to run on top of it. It is mounted on a DDM4V11.

I am tempted by the Trijicon RMR but having to unmount it to replace the battery is not something I want to have to do.

Thanks.
