Not sure if it’s a recurring theme yet, but there have been a few companies at SHOT here talking about their single-shot break-action rifles. There’s nothing super new for AAC, but they talked to me about their “Handi-Rifle” which comes in 300 AAC BLACKOUT.
It’s got a threaded 16.2″ barrel with a 1:7 twist. It weighs 6.9 lbs and felt very solid in my hands. It would probably make a very nice hunting rifle.
