My new Noveske 10.5" 300 Fireball in my LMT MRP. I had this barrel converted and dropped in in just before 300 Blackout was announced. I hope its fully compatible as commercial ammo will be a nice option in a pinch. Guess I plan to buy 300 Blackout dies. Anyway, what do you guys think? Will shoot it for the first time this weekend. I'm waiting for a thread converter and will try my Nexus III 45 pistol can at some point (only intend to shoot subsonic).
