Get to know 5.56:

Derived from and dimensionally similar to the Remington .223 cartridge, the 5.56x45mm NATO cartridge was selected at the first NATO rifle cartridge in 1954. In modern times, this round is often used during shooting competitions and is a common home defense and law enforcement replacement for shotguns; however, this cartridge is most often used in Armalite鈥檚 AR-15 style rifle and the similar rifles that have been developed as an alternative to them. Green Country Ammo is proud to be able to provide these 5.56x45mm NATO rounds that were loaded by our friends at Mead Industries.

The brass used for these 5.56x45mm NATO cartridges has been trimmed, sized, reamed and loaded again from previously-fired brass. This ammunition is lab tested to SAAMI specifications although headstamps may vary due to the unique processing requirements. Some cases will show a 223 headstamp, but will be loaded to 5.56x45mm NATO specifications. In most cases, this product is ready to ship within a week. Although, under times of unprecedented demand,聽these聽5.56x45mm NATO聽may take up to 3 weeks to ship.
