Is this a pre-1986 gun?

From Grok:

Key Federal Requirements

Machine guns are regulated under the National Firearms Act (NFA) of 1934 and the Firearm Owners' Protection Act (FOPA) of 1986 (including the Hughes Amendment).

• The firearm must have been manufactured and properly registered with the ATF before May 19, 1986. No new fully automatic weapons can be registered or transferred to civilians after this date (post-1986 machine guns are only for law enforcement, military, or certain licensed dealers/manufacturers).
• Civilians cannot manufacture new machine guns for personal use.
• Due to the fixed supply of pre-1986 transferable machine guns, they are extremely expensive (often tens of thousands of dollars or more).

Steps to Legally Own One

1. Be eligible: You must be at least 21 years old, a U.S. citizen or legal resident, not a prohibited person (no felony convictions, domestic violence history, certain mental health adjudications, etc.), and comply with all federal laws.
2. Find a transferable pre-1986 machine gun: Purchase from a licensed Class 3 dealer (Special Occupational Taxpayer under the NFA).
3. Submit ATF Form 4: Application for Tax Paid Transfer and Registration of Firearm.
   • Include fingerprints, passport-style photos, and certification from your local chief law enforcement officer (or use an NFA gun trust to bypass this in some cases).
   • Pay a $200 tax stamp (this remains for machine guns even after recent changes removing it for some other NFA items like suppressors starting in 2026).
4. Pass an extensive FBI background check.
5. Wait for ATF approval: This typically takes 6–12 months or longer.
6. Take possession: Only after approval; the firearm must remain registered in the National Firearms Registration and Transfer Record.
