For nearly 20 years, Mark Serbu’s SUPER-SHORTY has been the standard-bearer among the super-compact shotgun set. Built from either a Mossberg 500 or a Remington 870 that started life with a pistol grip, the S-S is considered an “Any Other Weapon” (AOW) under NFA law, meaning a $5 tax stamp instead of $200 as with other NFA items. I’m really not sure if most people buy these just for screwing around and having fun or if it’s for more practical purposes, but I do know that the S-S is capable of filling both roles. . .
