Last month, the Loudoun County Sheriff’s Department (LCSD) made headlines when they arrested a man for carrying a concealed firearm without a valid Virginia concealed handgun permit (CHP). What caught even more attention was their claim that his AR-15, fitted with a binary trigger, was technically a machine gun — a serious allegation that sparked quite the controversy.

What’s the Deal with Binary Triggers?

If you’re into firearms or outdoor shooting, you’ve probably heard about binary triggers. Simply put, these triggers allow a gun to fire one round on the pull and one on the release, effectively doubling your fire rate without full-auto capability. They’re legal in many states but often misunderstood by law enforcement and the public alike.

Why the Sheriff’s Department Flipped the Script

After the arrest, the Loudoun Sheriff’s Office stood firm on their claim at first, labeling the binary-trigger-equipped AR-15 as a machine gun under federal law. But once gun rights advocates, legal experts, and everyday shooters weighed in, pointing out that binary triggers don’t meet the legal definition of a machine gun, the department reevaluated their stance. The backlash was loud and clear — and ultimately, LCSD retracted their initial claim.

What This Means for Gun Owners and Outdoor Enthusiasts

This whole situation highlights the importance of understanding firearm laws, especially when it comes to newer gear like binary triggers. Whether you’re out in the field hunting, hitting the range, or just staying informed about your gun rights, knowing the ins and outs of your equipment and the law is key. Misunderstandings can lead to unnecessary arrests and legal headaches.

Final Thoughts

At the end of the day, the Loudoun County incident is a reminder that gun laws can be complex and sometimes misinterpreted — even by those enforcing them. For anyone interested in firearms, outdoor adventures, or gear
