MANCHESTER, Conn. — A 23-year-old Manchester man known to investigators as “Lavish David” is facing decades in federal prison after a grand jury in Hartford indicted him on charges that he smuggled machine gun conversion devices — tiny components that turn pistols into fully automatic weapons — into the United States from China.
David Williams Jr. was indicted on Oct. 14, 2026, on four counts tied to the importation and trafficking of the devices, according to the U.S. Attorney’s Office for the District of Connecticut. Williams has pleaded not guilty and is free on a $100,000 bond while awaiting trial. Like every defendant, he is presumed innocent unless and until proven guilty.
TL;DR: David Williams Jr., 23, of Manchester, was indicted Oct. 14 by a Hartford grand jury on firearms trafficking conspiracy, two machinegun possession counts, and smuggling. Federal prosecutors allege he ordered machine gun conversion devices — “Glock switches” — from China, concealed inside camping stove parts. He was arrested Oct. 2, pleaded not guilty, and was released on $100,000 bond.
Hidden Inside Camping Stoves
According to court documents cited by prosecutors, U.S. Customs and Border Protection officers at Chicago O’Hare International Airport examined a package en route from China to “Lavish David” at a Bloomfield, Connecticut, address in June 2026. Inside, agents allegedly found a machine gun conversion device concealed within portable camping stove components.
A second package, examined at New York’s John F. Kennedy International Airport, allegedly contained multiple conversion device components hidden the same way. Homeland Security Investigations later conducted a controlled delivery of the two packages to the Bloomfield address and confirmed that Williams had ordered the items delivered to the residence, prosecutors say.
Prosecutors also allege that a court-authorized search of Williams’ Apple account turned up photos, videos, and messages involving the possession of firearms and the trafficking of machine gun conversion devices.
What Is a “Glock Switch”?
A machine gun conversion device — commonly known as a “Glock switch” — is a small attachment that allows certain firearms to fire fully automatically, releasing many rounds with a single pull of the trigger. The devices are cheap to manufacture, often shipped from overseas, and have become a top enforcement priority for federal authorities because of their link to surging gun violence in U.S. cities.
Under federal law, an unregistered conversion device is itself classified as a machinegun, making its possession and importation a serious crime even if no complete firearm is ever assembled.
Charges Carrying Up to 55 Years Combined
The indictment charges Williams with four counts, each carrying a lengthy maximum sentence:
- Firearms trafficking conspiracy — up to 15 years in prison
- Unlawful possession of a machinegun — up to 10 years
- Possession of an unregistered machinegun — up to 10 years
- Smuggling goods into the United States — up to 20 years
Williams was first arrested on a federal criminal complaint on Oct. 2, 2026. He appeared in Hartford federal court and entered a plea of not guilty to all charges. A judge released him on a $100,000 bond pending trial.
Who Ran the Investigation
The case was announced by David X. Sullivan, United States Attorney for the District of Connecticut, and Jeff Grimming, Acting Special Agent in Charge of Homeland Security Investigations in New England. The investigation is being conducted by HSI and U.S. Customs and Border Protection, with assistance from the Manchester Police Department. Assistant U.S. Attorney Geoffrey M. Stone is prosecuting the case.
The Connecticut prosecution comes amid a broader federal crackdown on conversion devices, including a recent operation in which authorities seized more than 350 websites illegally selling gun parts shipped from China — the same supply pipeline alleged in the Williams case.
