Product Description
Presentation
Specna Arms meets players' expectations by introducing the FLEX product line, an exceptional series of replicas that bring superior quality to the market. The attractive price, combined with the innovative spring change system and high-quality materials, make the new SPECNA replicas the right choice for both experienced players and beginners.
The SA-F01 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-F01 replica is made of metal and glass fiber reinforced polymer. The metal components include the barrel, control buttons, and sling attachment system. The polymer components include the replica body, grip, stock tube, and stock itself.
This replica is equipped with ESA (Easy Spring Access). This system allows for quick spring changes without the need to disassemble the gearbox. The spring can be replaced by removing only the stock tube from the back. The barrel is made of metal and is covered with standard picatinny rails on all sides, allowing for extensive customization. The package also includes a classic folding and adjustable sight system.
Interior of the replica
The internal mechanism of the SA-F01 replica is made of metal. For added precision, Specna Arms has equipped the replica with a 6.03 mm precision barrel with a length of 220 mm. The gearbox features 8mm bearings, and the gearwheels are made of steel. The replica's piston is made of polycarbonate. Additionally, the replica comes with a Rotary hop-up chamber that allows for easy adjustment of the hop-up adjustment. The durability of the internal parts allows for the use of up to M140 springs. The muzzle velocity is 110-115 m/s when measured with 0.20g BBs. The package also includes an M90 spring, allowing for the use of the replica in most tight spaces. The replica is equipped with a GATE X-ASR mosfet.
Power Source
The package includes a hicap magazine for BBs and an M90 spring. We recommend not using batteries higher than 9.6V as it could damage the replica. For optimal performance, we recommend using only high-quality BBs. The use of low-quality BBs can damage the replica.
