More about 5.56x45mm NATO

State-of-the-industry loading techniques and quality control procedures ensure the reliability of Frontier Cartridge rounds, which feature brass cartridge cases and military-grade boxer primers and propellant. Loaded on the same assembly lines that ammunition for the US Military is loaded on, this ammunition passes strict quality specifications to ensure reliability and accuracy. This ammunition is new production, non-corrosive, in boxer-primed, reloadable brass cases.

Note: Frontier ammo is loaded using military spec primers designed to reduce the risk of slam fire.  These primers may not detonate in match tuned firearms with reduced power hammer or striker springs.

Please Note: While the 5.56x45mm will fit in a .223 Remington chamber, the 5.56 is a military round that runs at higher pressures than its .223 counterpart and is not recommended to be fired in a .223 Remington chamber.
