Legalities – National Firearms Act (NFA)
The X01 in its as-sold configuration with an arm brace or no rear attachment meets the ATF’s classification as a pistol.
- Adding a vertical grip to the X01 will transform it into an “AOW” and it will become an NFA item.
- Adding a buttstock to the X01 will transform it into an “SBR” and it will become an NFA item.
- If you intend to transform the X01 into an NFA item, please acquire your tax stamp or license before ordering as having both the X01 in an NFA configuration and the donor pistol readily available may constitute intent to manufacture / assemble.
For information on the legality of shouldering a pistol stabilizing device, see the ATF’s stance in an official letter here.
