80 Lower Receiver For Your AR-15 Platform

Dear JMT Customer,

With the additional scrutiny placed on the 80 lower receiver marketplace due to current events, JMT wants you to know we designed from the beginning our 80 lower receiver blank to conform with the FTB (Firearms Technology Branch) and ATF guidelines. JMT is being proactive and has submitted to the FTB our blank for the determination letter.
