Specna Arms' SA-H07 airsoft gun replicates the HK416C rifle in PDW configuration with Remington Defense trickle. The drive is predominantly made of zinc-aluminum alloy, reinforced with steel in the most loaded and critical places - in particular, all bolts are made of steel. antobok. For the telescopic stock, as well as the pistol grip, polymer is used. Receiver and forend with RIS system have a protective anodized coating, which significantly increases corrosion resistance. The paint is also characterized by increased resistance and durability: it is applied by powder method, and the corresponding surfaces have been previously sandblasted. The manufacturer's emblem is applied to the receiver

According to the manufacturer, all parts of the product are very precisely fitted to each other (at the level of analogs from top brands), and the weight balance is optimized as much as possible, making the drive very maneuverable, and its weight "is almost invisible when held in the firing position."

One of the design features of the product is the quick spring change system - ECS (Enter & Convert ™). This system allows you to adjust the drive to the characteristics of a particular landfill, even without having access to a workshop or special tools: just remove the hump box - and the spring can be replaced in a matter of seconds. The benefits of this design cannot be overstated given that different teams and organizations may have different drive power requirements. ECS allows you to install a replaceable spring with minimal effort and time, thus choosing the best initial ball velocity and providing an optimal balance between efficiency on the one hand and safety for the players on the other. It should be noted that the drive package includes a replaceable M90 ​​spring, ideal for close range combat, including in buildings. It reduces the initial velocity of the ball to 94 m / s, while the standard mainspring gives about 131 m / s and is designed for medium-range combat.

The drive is fully compatible with LiPo and LiFe batteries; Tamiya mini connector type, however, the battery and charger are not included in the scope of delivery.

One of the elements of the ECS system is a steel spring guide installed in a hump box. The gearbox itself has a reinforced design, uses 8mm ball bearings and steel gears, with four anti-reverse hooks on the motor gear. Also worth mentioning are the Type 2 cylinder, the steel fire baffle and the high-quality rotary hop-up chamber made of durable polymer, providing very precise and stable ball twist control.

The drive is equipped with a 22 mm RIS top rail and a trickle with RIS bars. Fixed sighting devices are mounted on the top bar, which, if necessary, can be quickly folded so that they do not interfere with the collimator or other optoelectronic device. The flame arrester is installed on a standard left-hand thread of 14 mm, which allows you to optionally replace it with a dummy silencer. Other interesting features include a fully functional shutter delay mechanism.

The telescopic example has a design identical to the combat prototype. Thanks to the anti-slip base, it can be locked in any intermediate position, which allows the length of the example to be very precisely adjusted to the needs of the player. It should be noted that, unlike many other Specna Arms actuators, this model does not have a buffer tube, and the example is fixed with a pair of movable rails. This reduced the length of the drive as much as possible and made it ideal for CQB (confined space combat at ultra-short distances). For the same reason, the location of the battery had to be changed - it is installed in a dummy AN / PEQ target designator attached to the forend (accordingly, the wiring in this model is brought into the forend).

The scope of delivery includes a steel hopper magazine for 300 balls. However, the drive is compatible with many third-party shops on the market, in particular with products from manufacturers: BOYI, Airsoft Systems, SRC, King Arms, MAG, STAR, ACM.
