Hey guys and gals, quick question for anyone who knows, I was looking at getting a mossberg 930 blackwater edition, I was doing some research here and apparently that weapon is considered an assault weapon?? So my question is, if I was able to purchase it would I just have to buy a normal cap for the tubular magazine and deep six the +2 extention and it'd be fine right? Or do I have to have it like welded on for permanence?? Any one got some insight into this? Appreciate the help.
