M4 Flex SA-F03 GATE X-ASR (Specna Arms)

The rifle features a factory-installed MOSFET X-ASR system from the Polish brand GATE. This is an unprecedented collaboration between a Polish manufacturer and a well-known airsoft replica factory. The highest-quality X-ASR MOSFET ensures the safety of the replica's components, improves trigger response and electronics and battery life, and allows you to diagnose basic internal malfunctions thanks to the integrated indicator LEDs.

Specna Arms presents a line of replicas - FLEX™ augmented with a GATE X-ASR MOSFET. An attractive price, coupled with an innovative spring replacement system and high-quality materials, makes this series particularly appealing to beginner airsoft players.

The body, free-float forend, slide, and battery housing the enlarged SF-type stock and pistol grip are made of nylon fiber-reinforced polymer. Aluminum alloy and ZnAl were used for the barrel, flashback arrestor, enlarged reloading grip, and triggers. All screws, pins, the ejection port, and the dummy lock are made of steel. The barrel is serially numbered.

The barrel has been very well adjusted; the user will not feel any play between the upper and lower parts of the barrel. The use of a lightweight plastic body and forend has reduced weight, making it an ideal replica for dynamic CQB games. In addition, the nylon fiber reinforcement makes the construction more durable than other polymer constructions.

The replica uses the ESA™ quick-change spring system. This allows you to quickly and efficiently adapt the replica's power to the expected conditions on the playing field without the need for access to a workshop or a range of specialized tools.

The replica has been fully adapted to operate with both LiPo and LiFe battery types. With a muzzle velocity of approximately 375 FPS guaranteed by the factory-installed main spring, the replica is ideal for medium-range operations. An M90-type spring is also included, which allows the muzzle velocity to be reduced to approximately 300 FPS, making the replica perfectly suited for close-range or indoor operations.
