FN FIVESEVEN 5.7X28MM 20RD AS BLACK Five-seveN 57

FN Five-seveN chambered in 5.7X28MM comes with 2×20 round mags. This is the version with black finish. The FN 57 shoots a bottleneck cartrigde and has very little felt recoil. While the muzzle velocity can exceed 2,350 ft/s.  Some people like Tim Kennendy has said they will use this as their EDC (Everday Carry) weapon since it is lightweight and high capacity.
