Description

The receiver, stock slide and an SF stock that holds the battery, as well as the pistol grip, were made from nylon reinforced polymer. Remaining components such as the barrel, KeyMod handguard, 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 replica’s 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. What’s more, fiberglass reinforcement makes the receiver also more durable than polymer and metal receivers. 
The replica features a ESA(TM) 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(TM) 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(TM) 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 muzzl..
