No, 300 BLK at 300 meters has 16.7% more energy than Lapua 7.62x39mm ammo. That means it is just a good way to get 30 round capacity of 30 caliber ammo in a normal AR with a normal bolt and normal magazines. All it needs is a barrel change.
So if you would not suppress an AK, then there is no reason to suppress a BLK.

Full-out-awesome, and I am very proud of the ammunition engineers for taking the dream-approach on this.
There will be no shortage of this. If the market wants a million rounds a month, it will get it. It has its own machines.
