RIFLE M4 CQB SA-C04 BLACK SPECNA ARMS (SPE-01-018319)

The body, and SF stock that contains the battery and the pistol grip are made of nylon fiber reinforced polymer. The remaining components such as the barrel, RIS handguard, flash hider, metal cocking lever (steel parts include screws, pins, shell ejection port and bolt carrier).

The parts of the replica are aligned very well and the user will not experience any loose spots between the lower and upper receiver. The use of a lightweight polymer receiver has allowed for a low weight, making it very suitable for long-lasting dynamic or mil-sim games. Additionally, the fiberglass reinforcement makes the receiver even more durable than polymer and metal receivers.

The replica is equipped with an ESA™ quick change spring system. Thanks to such a system, it is possible to quickly and easily adapt the power of the replica to the expected conditions on the playing field without the need to access a workshop or a set of special tools - all that is needed is to remove the butt pad to access the spring so that it can be removed without having to extract or disassemble the gearbox.

The gearbox contains 8mm plain bearings and shimmed steel gears based on them. The system is secured by four anti-reverse locks. A lightweight piston, made from a polycarbonate polymer, is fitted with an all-steel ring, in order to increase its life. In addition, a type 0 cylinder and a steel switch have been implemented, as well as a precise rotating Hop-Up chamber. The durability of the parts allows for cooperation with the M140 springs.

The precision rotary type Hop-Up chamber fits perfectly with the high-quality 6.03 precision barrel. The use of the precision barrel has a positive effect on the range and accuracy of the replica.

The replica features a 22mm RIS top rail, RIS handguard and adjustable stock. The upper RIS rail features a flip-up rear sight that does not collide with optoelectronic sighting devices. Thanks to the extendable stock with a non-slip pad, the length of the replica can be adapted to the body type and user preferences. A standard flash hider is based on a 14 mm left-hand thread, which allows for the attachment of a silencer in its place.

The set includes an S-MAG Hi-Cap magazine with a capacity of up to 380 BBs. S-MAG is an exclusive polymer magazine designed by Specna Arms. Of note is the distinctive texture made up of the Specna Arms logos. S-mag facilitates a continuous feed of BBs even at high ROF.
