Presentation

This airsoft replica offers a perfect advantage in airsoft battles in confined spaces, thanks to its compact dimensions, the materials used, and the accessorization possibilities. The materials used to manufacture this toy are lightweight and durable, and the execution quality is very good considering its price category. The airsoft replica package contains almost all the necessary elements to get it operational.

Exterior of the Replica

Impressive.... We can only praise the gentlemen at Specna Arms for the quality-to-price ratio they offer with their replicas. The exterior of the airsoft replica is well made, and the materials used are of high quality. Aluminum and aluminum alloys are employed, significantly reducing weight and greatly improving maneuverability. The design of the airsoft replica is both aesthetically pleasing and efficient. The front rail has ample space for various accessories. On the upper part of the body, there is a standard rail running almost the entire length of the airsoft replica, allowing for the mounting of a wide range of optical sighting devices.

A large part of the airsoft replica is made of metal, while the ABS plastic elements include the grip and the stock. The stock is adjustable with 6 positions and features a rubber pad for improved grip, and due to its considerable dimensions, crane batteries can be installed. The airsoft replica is equipped with a classic folding sight system, allowing the use of other sighting devices. Note that to operate the sighting system, the button on the left side must be pressed.

To add a touch of realism, the manufacturers have installed a system that mimics an active bolt catch, allowing for easier hop-up adjustment. The airsoft replica can be secured with a sling using the sling swivel positioned above the grip, and access to this attachment system is available on both sides of the replica. There is also a support point for the replica at the rear of the rail system, which is a QD type system. Note that the included sling is not intended for supporting the airsoft replica.

Interior of the Replica

The airsoft replica is equipped with a nearly standard version 2 gearbox, the only difference being the ability to replace the spring without opening the gearbox shell, but don’t get too excited, the gearbox still needs to be removed to perform this operation. Regarding the internals of the replica, we can say they are of good quality. The piston, its head, and the cylinder head are made of polycarbonate, while the gears are made of quality metal. The shimming of the airsoft replica is well executed, and the sound of the functioning gearbox is good. The motor of the airsoft replica is standard but successfully engages the internal mechanism, with a consumption of only 10-11A, indicating that it is a well-optimized gearbox. The performance is certainly aided by the gears equipped with 8 mm bearings.

The hop-up chamber is metal, and the adjustment is located inside the ejection port. It can be accessed by operating the cocking lever of the airsoft replica. The grouping is good even though the inner barrel has a diameter of 6.08 mm. When properly adjusted, the hop-up allows the replica to achieve quite significant engagement distances. The speed of the airsoft replica is approximately 115-120 meters per second measured with 0.20g BBs. The package also includes a spring rated for approximately 90-95 meters per second.

Power Supply

The package of the airsoft replica includes a 9.6V 1100 mAh mini crane battery that installs in the stock. It is recommended not to use batteries larger than 9.6V as it may damage the toy. LiPo batteries can be used but not exceeding 7.4V. Always use quality BBs and do not reuse BBs as it may damage the airsoft replica.
