idk if specifically the “super safety” has been tested but forced-reset triggers which are a slightly different thing got through ATF and a settled lawsuit.

i’m definitely not a lawyer but apparently “one shot per operation of the trigger” is the rule and mechanically resetting the trigger while you’re holding it down doesn’t count (neither do the safety nightmare “binary triggers” which shoot once normally and then shoot again on the way back to neutral).

probably they’re good unless your state bans them or somebody uses one in a mass shooting and trump bans them like bump stocks.
