Details, The GHK GKM is a replica of the AKM with a real wood stock and foregrip. The GKM has a 40 round magazine but a very large gas reservoir in the magazine meaning it can very efficiently empty a whole magazine with gas still to spare in the magazine. Firing at a pretty consistent 350 fps, it is powerful enough to engage out to short-middle range but still low enough for very short and indoor use making it useful for urban fighting sites and CQB. When the magazine is empty, the gun doesn't fire anymore. The bolt charge is on the right side of the gun, the magazine release is accessible equally from both sides and the fire selector is present on the right hand side of the gun. As with all Gas Blow-Back weapons, performance varies depending on ambient temperature and speed of firing. You MUST be 18 or over to purchase this.
