The FB Mini Beryl S223 is a select-fire rifle chambered in 5.56×45mm NATO, built by FB Radom in Poland. From its 235 mm (9.3 in) barrel, Hornady 5.56 NATO FMJ (M193) Frontier® (55 gr FMJ) leaves the muzzle at about 2954 fps (900 m/s), adjusted from the 508 mm test barrel the figure was measured in. Zeroed at 100 m, the bullet drops 127 mm by 200 m with 765 J (564 ft-lb) left. At the muzzle that is enough to defeat Drywall, Plate Glass, Pine Wood, Brick and Kevlar NIJ IIIA, and not enough for AR500 Steel. It feeds from a 30-round magazine.
Computed by the BallisticEngine engine for this barrel length, zeroed at 100 m, 15 °C, sea level, no wind.
