About Us

4140 Armory is a Marine Corps Veteran owned ammunition manufacturer producing military grade freedom seeds. Our mission is to provide our shooters with rounds you can bet your life on. Large scale manufacturers have a built in fail rate in their production. At 4140 Armory, that is unacceptable -- every round we produce must perform. Our manufacturing process utilizes computer controlled inspection and then we inspect every round by hand to ensure perfection.
