Transferable vs. Pre-86 Dealer Samples vs. Post-86/Post Sample Machine Guns: What Buyers Need to Know

If you’re searching for machine guns for sale on GunBroker, you’ve probably seen terms like transferable machine gun, pre-86 dealer sample, or post-86 sample. These classifications are critical—they determine who can legally own the firearm, how it transfers, and its market value.

This guide explains the differences so you can confidently navigate NFA machine gun listings.


What Is a Transferable Machine Gun?

A transferable machine gun is one that was legally registered with the ATF before May 19, 1986.

Who can buy a transferable machine gun?

  • Civilians (where state law allows)
  • FFL/SOT dealers

Transfer requirements: ( **see comment at right)

  • ATF Form 4 approval  
  • Background check
  • $200 tax stamp
  • Waiting period (often several months)

Why transferable machine guns are expensive:

  • The civilian registry closed in 1986
  • No new transferable machine guns can be added
  • High demand + limited supply = premium prices

What Is a Pre-86 Dealer Sample?

A pre-86 dealer sample machine gun (also called a pre-May sample) is a machine gun manufactured or imported before 1986 but restricted to licensed dealers.

Who can own pre-86 samples?

  • FFL holders with a Special Occupational Tax (SOT)

Key advantage:

  • Dealers can keep pre-86 samples even after giving up their SOT

Why they’re popular:

  • Lower cost than transferable machine guns
  • Long-term retention for licensed dealers

What Is a Post-86 Machine Gun (Post Sample)?

A post-86 machine gun refers to any machine gun manufactured after May 19, 1986.

Who can buy post-86 samples?

  • FFL/SOT dealers and manufacturers only

Special requirement:

  • Typically requires a law enforcement demo letter

Key limitations:

  • Not transferable to civilians
  • Cannot be kept if the dealer drops their SOT
  • Must be transferred or disposed of properly

Why they’re common:

  • Most modern machine guns fall into this category
  • Generally the most affordable option (for qualified buyers)

What does “No Law Letter Required” mean?

You may see listings that say:“Post sample – no law letter required”.

What it means:

  • The firearm can be transferred to a properly licensed FFL/SOT without needing a demo letter for that specific transfer

Why this happens:

  • SOT dealers can acquire post-samples without a law letter if buying the inventory from another dealer going out of business. 
  • This term applies only to licensed dealers (FFL/SOT) dealing with restricted weapons, not private citizens purchasing standard firearms.

What it does NOT mean:

  • ❌ It is not transferable to civilians
  • ❌ It does not remove NFA restrictions
  • ❌ It does not mean it can be kept without an SOT
  • ❌ It does not guarantee future transfers won’t require a demo letter

Why this matters to buyers:

  • “No law letter” is simply a transfer convenience for licensed dealers
  • It does not change the classification—it is still a post-86 dealer sample with all standard restrictions
