Shockwave Technologies sells a Raptor Grip that uses a profile similar to the “witness protection” style of some Reminton AOWs. It is similar to the SpeedFeed grip, but is longer and thus has a different grip angle. Due to the size, it can be installed on a pistol grip Mossberg 500 with a 14″ barrel, and will effectively increase overall length to 26.5″.
The resulting firearm would not be a Short Barreled Shotgun (SBS), as it has never had a buttstock (and thus has never been a shotgun). And it isn’t an Any Other Weapon (AOW), as it is not concealable (26″ maximum length to be considered concealable). This means it does not need to be registered with the NFA.
This is more human ingenuity fighting the senseless and arbitrary restrictions of the NFA registry. Like the Franklin Armory XO-26 and the CBRPS Romanian Draco Pistol Stock, this weapon mimics the features of an NFA firearm without requiring the time consuming and costly registration process.
