FN GUNR SS201 5.7x28MM 40gr FMJ Ammo, 50rd - 10700029

The FN-designed 5.7x28mm caliber, standardized in 2020 by NATO, was originally designed in the late 1980s for use with the military issued FN P90A(R) and FN Five-seveNA(R) pistol. With three decades of trusted use, the FN 5.7x28mm drastically improves range, accuracy and terminal performance from small arms with the hyper velocity bottleneck pistol cartridge.
