Accusations and Indictments

A twenty-five-year-old 1st Armored Brigade Combat Team member stationed at Fort Bliss, Texas, has been arrested for allegedly illegally manufacturing and selling parts that enable an AR-15 to be converted from semi-automatic to full automatic firing. The FBI is accusing Specialist Grant Lee Mosley of selling the parts online. He allegedly manufactured the parts using a 3D printer in his barracks room.

According to the Federal Bureau of Investigation’s official webpage, the arrest resulted from a multi-agency effort. Agents from the El Paso Field Office of the FBI worked with the US Army Criminal Investigation Division (CID), the Bureau of Alcohol, Tobacco and Firearms (ATF), and the US Postal Inspection Service (USPIS). Their combined efforts resulted in Mosley’s arrest. They state he is accused of manufacturing and dealing in firearms without holding a Federal Firearms License (FFL).

The specific part Mosely stands accused of allegedly manufacturing is the AR-15 auto sear. So, you may be thinking, what is an AR 15 auto sear? I’m glad you asked. According to our friends at the ATF:

“The auto sear known by various trade names including ‘AR15 Auto Sear,’ ‘Drop InAuto Sear,’ and ‘Auto Sear II,’ is a combination of parts designed and intended for use in
converting a weapon to shoot automatically more than one shot, without manual reloading, by asingle function of the trigger. Consequently, the auto sear is a machinegun as defined by 26
U.S.C. 5845(b).” 

Leave it to the federal government to confuse us a little bit. The United States Concealed Carry Association puts it a bit more succinctly; according to them, a sear is defined as “the part of the trigger mechanism which holds the hammer, striker or bolt back until the correct amount of pressure has been applied to the trigger. At that moment, the hammer, striker, or bolt is released to discharge the weapon.”

Mosley also allegedly made quarter-sized switches for Glock handguns. These turn the semi-automatic pistol into a fully automatic weapon capable of emptying a 30-round magazine in less than 2 seconds. See below.
