5.56 ammunition

The 5.56×45mm NATO (official NATO nomenclature 5.56 NATO, fyv-FYV-six) is a rimless bottlenecked intermediate cartridge family developed in the late 1970s in Belgium by FN Herstal. It consists of the SS109, SS110, and SS111 cartridges. On 28 October 1980 under STANAG 4172 it was standardized as the second standard service rifle cartridge for NATO forces as well as many non-NATO countries. Though they are not entirely identical, the 5.56×45mm NATO cartridge family was derived from and is dimensionally similar to the .223 Remington cartridge designed by Remington Arms in the early 1960s.

      1. For Trade
    • Corvallis
    • Oregon
    I acquired some 300 Blackout ammo in a trade, but I don't have a 300 blackout rifle. I have 40 rounds of Barnaul steel cased FMJ and 34 rounds of PPU brass cased hollow points. I'd like to trade for 223 or 556. Meet in Corvallis only for this little trade. Thanks!

    Did Garand Thumb change your go-to caliber? AKM vs M4 video

    What were your takeaways from the last video comparing 7.62x39 to 5.56? Changing up your defensive plans because of it? I for one was surprised at the lackluster performance from the 8M3 projectile. AKM vs M4
