We also offer discrete and overnight shipping to most countries across the globe.Buy FN 5.7×28mm (designated as the 5.7×28 by the C.I.P. and FN 5.7x28mm NATO) is a small-caliber, high-velocity, smokeless powder, rebated rim, bottlenecked centerfire cartridge designed for handgun and personal defense weapon (PDW) uses manufactured by FN Herstal. It is similar in length to the .22 WMR (5.7×27mm) and to some degree similar also to .22 Hornet or .22 K-Hornet. Unlike many new cartridges, it has no parent case; the complete package was developed from scratch by FN. The 6.5 creedmoor was developed in conjunction with the FN P90 PDW and FN Five-seven pistol, in response to NATO requests for a replacement for the 9×19mm Parabellum cartridge.
