Haven't seen or heard anything from Mossberg, but these barrels showed up on AIM Surplus...

Mossberg 16" .300 BLACKOUT AR Barrel

New Mossberg 16" .300 BLACKOUT caliber barrels for AR type Rifles. These high quality barrels feature a complete inside and out Melonite coating, 1:7 twist and M4 feed ramps.

Specifications:
- .300 BLACKOUT Caliber
- 1:7 Twist Rate
- M4 Feed Ramps
- Carbine length gas hole
- Uses .750 gas block (not included)
- Muzzle thread pitch 5/8x24

Not sure if they plan on a .300 BLK MMR, but these barrels showing up certainly point to the possibility...
 
I hadn't heard anything either, but it is good to see them.

That is also a good price too.

Wish it was about 9 inches and pistol gas :)
 
I haven't heard anything from Mossberg YET but I know they were looking into other calibers. The other side of the coin is that Mossberg makes barrels for TONS of companies and these could be surplus from an order.
 
there is talk that these are the exact same as the ati barrels...

there is also talk of inconsistent gas port diameters some .90 some 1.20...

I was thinking of contacting Mossberg directly and asking about these but I doubt I'll get any solid info and cs is probably clueless that they even exist.
