📅 2026 Update: Changes in Semi-Automatic Weapons Law

Since the original article was written, there have been several important changes to laws regarding semi-automatic weapons in the U.S. These updates include significant court rulings and new state laws that affect how these firearms are classified and regulated. For readers interested in the earlier discussions about semi-automatic weapons, that information continues further down the page.

⚖️ Supreme Court Rulings

In June 2024, the Supreme Court made a major decision in *Garland v. Cargill*. The Court ruled that semi-automatic rifles fitted with bump stocks are not considered machine guns under federal law.

This overturned the ATF's 2018 classification that labeled bump stocks as machine guns.

🚫 Colorado's New Law

On August 1, 2026, Colorado enacted Senate Bill 25-003. This law bans the sale, purchase, manufacture, and transfer of most semi-automatic rifles and shotguns with detachable magazines. It also includes restrictions on gas-operated semi-automatic handguns with detachable magazines.

💰 Current Fees and Processing

For those interested in machine guns, the National Firearms Act requires a $200 transfer tax for machine gun transfers. Current processing times for individual applicants submitting Form 4 for machine gun transfers are under 30 days as of early 2026.

📌 Key Points Summary

  • ⚖️ Supreme Court ruled bump stocks are not machine guns.
  • 📜 DOJ settled on specific FRT models, easing restrictions.
  • 🚫 Colorado banned many semi-automatic firearms as of August 2026.
  • 💰 $200 transfer tax applies to machine guns; processing times are under 30 days.

💡 Tips for Understanding Semi-Automatic Weapons Law

Reviewing your personal situation with an attorney is crucial to understand your rights and obligations regarding semi-automatic weapons.

📋 Know the Definitions

Understanding the definitions of terms like "machine gun" and "semi-automatic firearm" is essential. A machine gun is a weapon that can fire multiple rounds automatically with a single trigger pull, while a semi-automatic firearm fires one round per trigger pull and loads the next round automatically.

✅ Background Checks Required

All firearms purchased from licensed dealers require a background check through the National Instant Criminal Background Check System (NICS). This applies to rifles, shotguns, and handguns.

🎯 Age Restrictions

Federal law mandates that individuals must be at least 18 years old to purchase rifles and shotguns. For handguns, the minimum age is 21 when buying from licensed dealers.

🔄 Transfer Procedures

If you are transferring a machine gun, you must submit Form 4 to the ATF along with the required $200 transfer tax. Ensure all forms are completed accurately to avoid delays.

📅 Watch for State Laws

State laws vary greatly regarding semi-automatic firearms. Some states have enacted stricter laws, like Colorado's ban on certain models. Stay informed about laws in your state to ensure compliance.

🔍 Understand FRT Legality

Forced reset triggers (FRTs) are currently legal under federal law following a settlement by the DOJ. However, check your state laws, as some may still impose penalties for their use.

End of October 2026 Update





Automatic weapons are those which reload without any action from the shooter. The sequence of events, which begin with pulling the trigger, allow the gun to continuously reload. The gun also continues to fire when the shooter pulls the trigger just one time and holds the trigger until they want the gun to stop firing. Semi-automatic weapons are very similar to automatic weapons, except that they only fire one bullet with each trigger pull.


Automatic weapons are often used in wars. Soldiers can focus on aiming the automatic weapons, rather than reloading. Once the trigger is pulled, they simply move the gun as the target moves. However, automatic weapons can jam and if the shooter becomes injured and they release the trigger, the gun will stop firing. Technology on automatic weapons has become much more stable, lessening the chance that the gun will jam.


Semi-automatic weapons are also used in wars. The gun can also be prone to jamming. However, they are highly effective because the shooter simply needs to pull the trigger for each shot and does not have to be concerned with loading the weapon, as it does it automatically, in the same way that an automatic weapon does. The action of firing the weapon, allows the weapon to pull in more ammunition. The only difference between an automatic weapon and a semi automatic weapon in the need to continuously pull the trigger on a semi automatic weapon.
