Strange question: 6.5 flash hider on a 5.56 rifle

Re: Strange question: 6.5 flash hider on a 5.56 rifle

do you mean "would it hide the flash just as well"?

or do you mean "would it be completely useless"?

or do you mean "will it even fit"?

I've been wrong before, but you could come across a different thread pattern. Probably depends if you're talking about a Creedmore or a Grendel.
