Mossberg introduces their "Shockwave" 14" barrel "non-NFA" 12ga. pump shotgun at the 2017 Shot Show. The gun is fully BATFE compliant being 26" overall. I still am not 100% clear on how this precludes the 18" barrel rule, but who am I to look a "gift horse in the face? Check it out HERE. I bet they sell a ton of them too.
