5.56mm NATO for AR-15 Platform
The 5.56 NATO is the classic cartridge for the AR-15. Its popularity is largely thanks to its rapid rate of fire, minimal recoil, and excellent accuracy. It originated as a military cartridge, serving primarily in infantry fighting over the past several decades. The 5.56 AR-15 works well as a coyote and varmint hunting cartridge that can also step into deer.
