It was shooting hot for me but I'd only ever chrono'd it so assumed it was a tight spring due to zero use. Hope you're happy with it, looks great with the changes, did you empty the Pmag for the battery or reroute the wiring?
Think I'd only ever fitted an RDS to the top rail so can't comment on the rest of them.
I remember watching Forgotten weapons vids about his AR57 & apparently the RS charging handle was dodgy... I should have charged more for the realism 😉
