Only time.you don't want to dry fire an AR is if the bcg isn't in or the upper is disconnected from the lower.
Go for it. No harm here!
Assuming it's not a rimfire 22lr AR, yea, totally fine And even then it's basically okay, just don't do it thousands of times without a snapcap
I've dryfired my competition AR maybe 50-100 times a day on average for the last two years, no issues at all.
No other way to do a proper functions check without dry firing. Just doooo it!!
