    1. The minute you take off the factory rear grip and put something else on that gun your’re in a gray area. Why not just use it in the stock configuration and be glad the BATFE found no objection to that? The next thing you know they’ll have another letter out rescinding the original OK!

    2. Unless they released another statement since last I checked, you’ve posted a photo of a felony taking place. (Unless that’s a registered sbs)
      You can shoulder the brace fitted on a rifle, but not on a shotgun, and not on either neither with the “blade” stabilizer. Just trying to look out lol

      1. Wrong! Completely legal as a non NFA smooth bore firearm. Been that way for at least five years before Mossberg even made a factory version with a brace on it. Get with the program will ya?

    3. All right! Another fat guy with a gun. Weapon handling is a discipline. Your platform to present one should also be disciplined. How far can this obese guy run to find cover? Maybe the tats help scare the bad guy… This picture is all too common now a days. Very sad indeed.

      1. @Gene, Maybe, this chubby fellow has thought out his defense, in advance, taking his own limitations into account… like all good commanders. Maybe he has a pre-prepared position near by or this is part of the resupply. Or maybe it is just an advertisement.

      2. Unless you’re trying for some kind of humor or sarcasm, I fail to understand your concern. I can think of MANY other weapon handling disciplines more important than what the practitioner “looks” like. And, I sincerely hope that you’re not saying that people who don’t have the physical prowess of a Navy SEAL or Spec Ops tactician shouldn’t be allowed to handle or operate a defensive tool?

        Firearms are THE great equalizer, allowing those of us with physical difficulties, of any kind, to meet life-threatening challenges on a more level playing field. As a 73-year double knee replacement patient undergoing the ensuing physical rehab, who will always struggle with degenerative disc disease, I appreciate firearm products INCLUSIVELY being demonstrated by folks that look more like the real, common folks that’ll be using them and not just “Gym Rat” tacti-cool wannabe models that look like Vin Diesel.

        Also, just for what it’s worth, and judging only from this one picture, I wouldn’t feel seriously disadvantaged to be on the same team as the guy demonstrating this Mossberg, or Tyrus, the even bigger and tatted professional wrestler/professional bodyguard!
