HFC exclusively features a mini grenade launcher that attaches to your pistols, machine guns and rifles. A more than interesting option to take our pistol with a small device with which to shoot 40 balls with a single shot. Made of aluminum, runs on green gas and can be attached to any standard railing / picatinny system. And best of all is that this grenade launcher can be mounted both on a gun and on a rifle given its small dimensions.
