Mach Sakai checks out the GHK AK74 FAB Custom, a gas blowback airsoft rifle that has been modified for a modern look. He examines the various tactical additions, including the FAB Defense style handguard and stock, while noting the substantial weight of about 4.1 kilograms. This heft seems to help manage the recoil, though it might give your arms a bit of a workout if you plan on carrying it all day.

During the performance test, the rifle demonstrates a satisfying metallic sound and a kick that adds to the realism. Sakai tests the muzzle velocity and accuracy, observing that the hop-up effect is quite strong even with different BB weights. He finds the trigger pull to be relatively light and crisp, which makes the shooting experience enjoyable, even if the gun's weight makes rapid target transitions a bit slower than usual.

As the session continues, the gas efficiency shows its limits in cooler temperatures, with the rate of fire slowing down as the magazine chills. Sakai concludes that while the rifle has its quirks, such as a very stiff magazine loading process and temperature sensitivity, it offers a great deal of romance for fans of modernized classic firearms. It is a solid choice for those who value a realistic feel and don't mind a bit of a heavy lifting session at the range.
