attachment IDEE for some weapons (NOT GRENLAUNCHER OR FORBIDDen)

hello im thinking maybe it would be cool if there was an weapon attachment for like snipers or assualt riffles or annything u want but il start saying my idee: A attachment that haves the effect of an flashgrenade when u shoot but only for 1 sec or less just that when u shoot in his legg or just iss him hes blind for 1 or even 0.1 second as sniper u then have abillaty to shoot whyle he haves a stunned sicht.


WHEN U THINK THIS IDEE SUCKS SAY IT PLZ XD
