Okay, I'm trying to better understand the definition of a pistol in regards to an AK build. My specific question is in regards to the front handguard. Is it true that it have a vertical front grip under federal law? So to use a vertical front grip on a short barrell does it have to be registered as an SBR?
Also, if the pistol uses an unmodified front handguard will you catch flack having a spare vertical grip in your spare parts collection?
