Buy the 500SP with the adjustable stock for half the price of the 590 and the expensive add on.


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


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?


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.

@Roy, 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.

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.

He IS cover.


Whoa! Gene the operator has entered the chat.

Going from the military to bouncing to nursing I have learned it is best not underestimate anyone. If that boy doesn’t explode hearts with that double aught then he probably will with his bare hands.

Sounds like you are training awfully hard to just be a keyboard warrior Gene.


Hey Gene, over the last 20 years of shooting IDPA and USPSA I have seen quite a few “fat guys” running and gunning. And they did it well enough that they were ahead of me in the scoring. I would not have wanted any of them shooting at me.

Check your state laws first


G I really don’t see why they don’t make those non-NFA everyone needs a brace on that thing


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!


They will rescind it once the Executive is blue again. What you really need to ask yourself is what did the Framers believe about rights? Are they God given or are they man-given?
