With 300BLK Subsonic, pressure is not a concern, only bullet stabilization. It has a 1:6 twist rate which would stabilize the bullet just fine.
From Gemtech:
"Our guideline for barrel minimum length, is caliber specific - not can specific;
Minimum barrel length on 308 is 16", for 5.56 it's 10.3".
For 300BLK SBR's minimum is 1/2" longer than your twist rate - 1in7 = 7.5" - 1in8 = 8.5" - 1in9 =9.5"."
Probably just a warranty issue. With that fast twist rate I would think it should be fine. I plan on getting a 300 MCX SBR and the Omega is what I am going to get for it.
