I just got my new Mossberg ShockWave 12 gauge shotgun pistol on Monday and I am loving it! So if you didn’t know, a normal shotgun has to have a barrel length of at least 18 inches and an overall length of 26 inches. It also has to have a shoulder able but-stock. Anything else is normal classified as a short barreled shotgun (SBS) by the National Firearms Act. Mossberg found a loophole in the law that allowed them to manufacture the ShockWave and sell it without requiring an NFA tax stamp. It is basically a 12 gauge pump action shotgun with a Raptor pistol grip by SHOCKWAVE. It has a short 14 inch barrel. And it is totally legit. Well anyway, I have one now, and I have given her a name as usual. I call her REBA. She is a real FBI nut-kicker.
