Specna Arms M4 SA-A05

Overview

This airsoft replica provides a significant advantage in airsoft battles in confined spaces, thanks to its compact dimensions, the materials used, and its excellent accessorization options. The materials used to manufacture the toy are lightweight and durable, and the execution quality is very good considering its price category. The package includes 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 utilized, significantly reducing weight and greatly improving maneuverability. The design of the airsoft replica is both aesthetically pleasing and efficient. The front system is of the Free-Float type, providing ample space for various accessories. There is a standard rail along almost the entire length of the airsoft replica's upper body, allowing for the mounting of an advanced sighting device.

A large part of the airsoft replica is made of metal, while the ABS plastic elements include the grip and stock of the airsoft replica. 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 foldable sighting system, allowing for 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 adjustment of the 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. 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 casing, but don’t 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 that it is a well-optimized gearbox. The performance is undoubtedly aided by the 8 mm bearing gears.

The hop-up chamber is metal, and the adjustment is located inside the ejection port. It can be accessed by operating the charging lever of the airsoft replica. The grouping is good even though the inner barrel has a diameter of 6.08 mm. When correctly adjusted, the hop-up allows the replica to achieve considerable 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 that provides approximately 90-95 meters per second.

Power Supply

The package 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. Always use quality BBs and do not reuse BBs as this may damage the airsoft replica.
