Product Description
Presentation
Specna Arms meets players' expectations by presenting the FLEX product line, an exceptional series of replicas that introduces superior quality to the market. The attractive price combined with the innovative spring change system, as well as high-quality materials, make the new SPECNA replicas the right choice for both experienced players and beginners.
The SA-F02 Flex replica features licensed markings from the firearms manufacturer Rock River Arms. Rock River Arms is a manufacturer of components and accessories, but above all, a manufacturer of high-quality AR-15 carbines.
Exterior of the replica
The exterior of the SA-F02 replica is made of metal and glass fiber-reinforced polymer. The metal components are: the barrel, control buttons, and sling attachment system. The polymer components are: the body of the replica, the grip, the stock tube, and the stock itself.
This replica is equipped with ESA (Easy Spring Access). This system allows for quick spring change without the need to disassemble the gearbox. The spring can be replaced through the rear part by simply removing the stock tube. The barrel is made of metal and is covered with standard picatinny rails on all sides, facilitating a wide range of accessories. The package also includes a classic folding and adjustable sight system.
Interior of the replica
The internal mechanism of the SA-F02 replica is made of metal. For added precision, Specna Arms has equipped the replica with a 6.03mm precision barrel with a length of 220mm. The gearbox is equipped with 8mm bearings, and the gears are made of steel. The replica's piston is made of polycarbonate. Additionally, the replica is equipped with a Rotary hop-up chamber that allows for easy adjustment of the hop-up adjustment. The durability of the internal parts allows the use of springs up to M140. The muzzle velocity is 110-115 m/s measured with 0.20g BBs. The package also includes an M90 spring, which allows the replica to be used in most tight spaces. The replica is equipped with the GATE X-ASR mosfet.
Power source
The package includes a hicap magazine for BBs and an M90 spring. We recommend not using batteries larger than 9.6V as the replica may malfunction. For optimal performance, we recommend using only high-quality BBs. Using low-quality BBs can damage the replica.
