The FN 57 Gas Blowback Pistol (CO2) airsoft gun is a fantastic model licensed from FN Herstal in Belgium. This full gas blowback action CO2 pistol is made in Japan by Marushin, so you know the quality is amazing on it right out of the box. We're very impressed with its accuracy, quality build, and shooting characteristics. While the FPS is less than other guns, the CO2 cartridge will last much longer than other pistols too. Full FN 57 trademarks too.
