Product Description
Brief History
It appeared on the battlefield in 1948, but the concept's creation began in the last year of World War II. This weapon has managed, from the very first moment to the present, to become one of the most versatile weapons of the century due to its robustness, reliability, and simplicity. Designed to incorporate the best aspects of the most renowned weapons of the time, it is still successfully used today without major interventions on its operating system. The manufacturer CYMA successfully integrates the best features of this weapon into their airsoft replicas.
Exterior of the Replica
The body of the airsoft replica, the grip, the stock, and the handguard are made from quality ABS plastic. The construction of the replica follows the Tokyo Marui model, meaning the front part and the body of the airsoft replica are assembled with 4 screws. This model facilitates access to the inner barrel and the Hop-Up chamber. The metal elements include: the outer barrel, the connection elements of the airsoft replica, the dust cover, the sights, and the mag-catch button. The stock of the airsoft replica has two positions, making it easier to operate in the playing field. To adjust the stock, the button on the left side of the stock hinge must be pressed. In the collapsed position, the stock offers good maneuverability in tight spaces. In the extended position, the stock provides good stability for the airsoft replica, allowing for much easier aiming.
Interior of the Replica
The Hop-Up adjustment is located inside the ejection port; this adjustment is linear and precise. The Hop-Up chamber is made of ABS plastic, which should not be a concern, as the casting quality is very good, thus there are no issues with feeding BBs. The precision and consistency of the airsoft replica are good.
The gearbox is version 3, known for being a durable version. It is, of course, made of metal, as are the gears. The piston, piston head, and cylinder head are made of polycarbonate. The BB speed is somewhere between 110 and 115 meters per second measured with 0.20g BBs. It is recommended to use 0.25g BBs for optimal performance.
Power Supply
To access the battery compartment, it is necessary to press the button above the grip and remove the dust cover. The maximum recommended battery is 9.6V, as using a larger battery poses a risk of damaging the toy.
