Product Description:
“Specna Arms meets the expectations of clients by presenting the CORE line of products - an exceptional series of replicas that introduces a new quality to the market. An attractive price in combination with an innovative spring change system as well as high-quality materials make this replica suitable for beginners and seasoned airsoft players alike.
The receiver, stock slide, handguard and a SF stock that holds the battery, as well as the pistol grip, were made from nylon reinforced polymer. Remaining components such as the barrel, flash hider, enlarged charging handle and tactical sling swivels were made of metal (parts made of steel include the screws, pins, shell ejection window and mock bolt carrier). The receiver bears markings and a serial number.
The replicas parts fit very well together and the User will not experience any loose spots between the lower and upper receiver. The use of a light polymer receiver allowed for a reduced weight, which makes it very suitable for dynamic games or long-lasting mil-sims. Whats more, fiberglass reinforcement makes the receiver also more durable than polymer and metal receivers.
The replica features a ESA Quick Spring Change System. Due to that system, it is possible to rapidly and quickly adapt the power of the replica to the conditions expected on the playing field without the necessity to have the access to a workshop or a set of special tools - all that is required is to remove the stock slide in order to gain access to the spring so that it can be removed without having to pull out or disassemble the gearbox.
The advantages of ESA system are hard to overstate. In the light of the current internal regulations inside various groups, the system guarantees the User a varied set of possibilities and plenty of freedom. ESA system allows with a minimal amount of time to change the main spring, thusly customize the muzzle velocity towards the area of the game in such a way so as to guarantee an ideal compromise between the effectiveness of fire and safety for the User himself as well as other participants.
The replica is fully compatible with LiPo and LiFe batteries. Due to a base muzzle velocity of ~380 FPS provided by the main spring installed by default by the manufacturer, the replica is perfect for operating on a medium range. The set also includes an M90 spring, which allows reducing the muzzle velocity to ~310 FPS and as a result to adapt the replica for close-ranged and indoor operations.
The gearbox contains 8 mm slide bearings as well as shimmed steel gears based on them. The system is secured with four anti-reversal latches. A light, made of a polycarbonate polymer piston is equipped with a full steel strip, in order to increase its durability. Also, implemented were a type 0 cylinder and a steel circuit-breaker, as well as a precise rotary Hop-Up chamber. The durability of parts allows for the cooperation with M140 springs.
The precisely-made rotary type Hop-Up chamber perfectly fit with high quality 6,03 precision barrel. The use of precision barrel has a positive effect on the range and accuracy of the replica.
The replica is equipped with a 22 mm top RIS rail and an adjustable stock. The top RIS rail features a classic transport handle along with a rear sight. Due to the extendable stock with an anti-slip stock pad, it is possible to adapt the replicas length to the body type and preferences of the User. A standard flash hider is based on 14 mm left-handed thread, which allows the attachment of a silencer in its place.”
