I know zero about these, but I do have a question asked out of ignorance. If you have rifles chambered in each, is there a possible of a .300 Blackout/5.56 kaboom if you mixup ammo? Or is this a non-issue because they could never chamber one in the other?
I had the question posed to me and truthfully answered that have no idea. I also have no desire to own either.
Thanks.
