My next AR would have been a 7.5" 300 BLK, but I just traded for a Ruger AR 556 so the factory ar came before the home build. But this week when my barrel comes in, the pistol will come in a close second and will probably see a lot more use as well. I am building the 300 BLK to be my truck gun.
As far as AR's becoming a fad, I don't have my AR's to be fashionable.

You should make the 300 black out the house gun and put a suppressor on it. I know if your shooting intruders in the house, ear pro is not high on the list, but would help with keeping ears in tact. (All coming from me, who uses an unsuppressed 556 for the house). Just a thought.
