I like that the Holosun has the RMR foot print and the 65 moa circle and dot but wondering if the reliability has gotten better. I built a Polymer 80 G19 lower, and will put the Brownells RMR cut slide, Ameriglo suppressor sights, and threaded barrel on it. Final piece will be the RDS either the 507c ( if the bugs are worked out) or the LED RMR( which are not totally without its own issues). Are any GTers running the Holosun 507C, if so what has your experience been. Same for RMR users.
