5" 300BLK barrel with suppressor?

A friend of mine brought this to my attention and it was a bit of a head scratcher to me. He showed me a pic of a 300BLK AR platform using a 5" 1:7 barrel, running a SilencerCo Omega 9K suppressor. By design I'm guessing it's suppose to run subsonic only. Still, I was always under the impression that you need about 9" of barrel to properly cook off all the propellant. With a 5" barrel pushing a 208-220gr projectile at maybe 900fps, isn't that going to cause a bit of wobble? Baffle strike?

Plus, Pmags for 556 doesn't like feeding fat/subsonic 300BLK ammo, too.

What say you?
