NASHUA – Firearms distributor KBC Capital recently pleaded guilty to 26 violations of the National Firearms Act.

According to court documents, one of KBC’s products, marketed as a muzzle break, was actually a silencer, a device used to reduce the sound of a gunshot. Other products included adapters, slide lock levels and trigger connectors.

KBC, which did business for 10 years as Lethal Eye, attempted to protect itself from criminal liability by using the disclaimer: “Buyer understands that these are not suppressors and or silencers in any way shape or form.”

From April 2020 to August 2023, KBC mailed 26 illegal gun accessories, including silencers, to customers in Massachusetts. However, according to Massachusetts General Law, it is illegal for Bay State residents to own silencers.

In addition, under the NFA, KBC was required to pay taxes on the products that were being shipped. The NFA also required that KBC be a Federal Firearms Licensee and pay a special occupational tax. Investigators later learned that the company never fulfilled any of the federal requirements.

While searching KBC’s primary place of business at 12 Murphy Dr. last August, investigators reportedly seized 327 silencers, five guns as well as “several hundred silencer endcaps and associated parts.”

According to the Plea Agreement, KBC will be fined $260,000 for violating NFA regulations. That amount will be paid in 12 installments ending in March 2026. The company will also be on probation for three years and will pay a special assessment of $10,400.

“By making gunshots harder to hear, silencers impede law enforcement efforts to respond to shootings and diminish the effectiveness of gunshot detection technology. This results in slower response time by first responders, which can have a direct impact on saving the lives of people struck by gunfire,” said Acting U.S. Attorney Joshua Levy. “That is why Congress and federal agencies require manufacturers and distributors of silencers to conform to strict regulatory requirements. By knowingly flouting these regulatory requirements, KBC Capital allegedly flooded the market with these inherently dangerous devices. This case demonstrates our office’s efforts to attack the problem of illegal guns from all angles.”
