I've been reading a lot of the posts regarding the legality of putting magazine extensions, collapsable stocks, etc. on the M1, M3, and M4 shotguns due to the import gun laws (regardless of the AWB sunset).
I recently purchased a Nova Tactical shotgun (my first shotgun and first Benelli!) and have ordered (but not installed) the two round magazine extension. My question is if it's legal for me to install that on my Nova? Is it an imported gun or does it fall into the same group as the M1, M3, and M4 regarding the legality of modifications?
Thanks for your help!
