Specna Arms M4 SA-A04

Overview:

This airsoft replica offers a significant advantage in airsoft battles in confined spaces, thanks to its compact dimensions, the materials used, and its excellent accessorization options. The materials from which this toy is made are lightweight and durable, and the quality of execution is very good considering its price category. The airsoft replica package includes almost all the necessary elements to get it operational.

Exterior of the Replica:

Impressive.... We can only commend the gentlemen at Specna Arms for the quality-to-price ratio they offer with their airsoft replicas. The exterior of the airsoft replica is well-made, and the materials used are of high quality. Aluminum and aluminum alloys are utilized, significantly reducing weight and greatly improving maneuverability. The design of the airsoft replica is both aesthetically pleasing and efficient. The free-float front rail system provides ample space for various accessories. On the upper body, there is a standard rail running almost the entire length of the airsoft replica, allowing for the mounting of advanced 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 sighting system. The rear part is foldable to allow 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 using the 4 quick-detach connection points located on both sides of the free-float front rail and with the sling swivel. Note that the included sling is not intended for supporting the airsoft replica.

Interior of the Replica:

The airsoft replica features a nearly standard version 2 gearbox, the only difference being the ability to replace the spring without opening the gearbox casing, but do not get too excited, the gearbox still needs to be removed to perform this operation. Regarding the internal components, 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 done, 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 it is a well-optimized gearbox. The performance is certainly aided by the 8mm bearing gears.

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 assembly is good even though the inner barrel has a diameter of 6.08 mm. When the hop-up is correctly adjusted, the airsoft replica can achieve quite large engagement distances. The speed of the airsoft replica is approximately 120-125 meters per second measured with 0.20g BBs. The package also includes a spring that provides approximately 90-95 meters per second.

Power Supply:

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