You would have to have 10 or less imported parts from the batf 922r list of parts to be legal. Many will say to ignore it... I won't. I was looking at one but can't find how many parts we'd have to replace or any one who makes us made parts.
You can get US made parts for benelli m1,m2 and Stoeger M3K,M3000.
None of this applies to Versamax since it's US made.
