EL PASO, TX— Agents from the FBI El Paso Field Office, the Bureau of Alcohol, Tobacco, Firearms, and Explosives-El Paso Field Office (ATF), the U.S. Army Criminal Investigation Division (CID), and the U.S. Postal Inspection Service (USPIS) El Paso Field Office and New Jersey Field Offices, worked collaboratively on a case that culminated in yesterday’s indictment of 25-year-old Fort Bliss soldier, Grant Lee Mosley, for allegedly manufacturing and dealing in firearms without being a federal firearms licensee.

Mosley was manufacturing 3-D printed AR15 auto sears, which would convert a semi-automatic firearm system in nature to a fully automatic firearm. Mosley advertised and sold handgun machine gun conversion devices (commonly referred to as switches) and auto sears on a social media platform across the United States in violation of the law.

“Reducing violent crime in our community and throughout our country is a priority of the FBI,” said FBI El Paso Special Agent in Charge Jeffrey R. Downey. “The collaborative work from multiple FBI Field Offices, ATF, USPIS, and Army CID, to disrupt the manufacturing and selling of these devices will ensure these illegal parts do not get into the hands of individuals who want to commit violent acts in our communities.”

“I could not be more pleased with the outcome to date in this joint investigation. Cases like this highlight the importance of authentic relationships between law enforcement agencies to keep our communities safe,” stated ATF Dallas Field Division Special Agent in Charge Jeffrey C. Boshek II. “Working with our partners, to include the FBI, Army CID, and USPIS, we were able to stop the illegal and highly dangerous proliferation of countless machine gun conversion devices. These devices, in the wrong hands, can have catastrophic consequences.”

“Today’s arrest underscores CID’s unrelenting resolve to hold accountable anyone within our ranks who engages in criminal activity,” stated Acting Special Agent in Charge Ray A. Rayos, Southwest Field Office, U.S. Army Criminal Investigation Division. “This case is another example of CID’s commitment to our law enforcement partners to make our communities safe.”

“The U.S. Postal Inspection Service is committed to ensuring the U.S. Mail system is not used as a tool to distribute dangerous and illegal items to our communities,” stated Scott Fix, Inspector in Charge of the Houston Division of the USPIS. “Postal Inspectors will continue to collaborate with our law enforcement partners, including the FBI, ATF, and Army CID to investigate and hold accountable those who use the U.S. Mail to facilitate their criminal behavior.”

It is important to note that a federal indictment is merely an allegation and should not be considered as evidence of guilt. A defendant is considered innocent unless and until proven guilty. Mosely faces up to 5-10 years per count in federal prison and up to $250,000 per count if convicted.

The FBI’s El Paso Violent Crimes Task Force, FBI Newark-Atlantic City Resident Agency, FBI Jacksonville-Daytona Resident Agency, ATF-El Paso Field Office, Army CID, USPIS-Philadelphia Division-New Jersey Field Office, USPIS-Houston Division-El Paso Field Office, the Atlantic County (NJ) Sheriff’s Office, and the Defense Criminal Investigative Service jointly investigated this case with the assistance from the United States Attorney’s Office Western District of Texas.
