Arcturus M4/M16 AR15 CQB AEG Airsoft Gun

Out of Stock

The newest AR15 -10.5". rifle from MOS factory. Arcturus AR15 is reliability and timeless design.

For years, MOS has been gaining experience, producing items for firearms as well as for the largest companies from the ASG industry.

The replica was made accurately and carefully.
The classic upper receiver is connected to a light M-LOK hand guard.

Most of the outer elements such as the upper and lower receiver, the outer barrel and the receiver extension are made of aluminium and light alloys. And the whole was secured with an anode.

The flame suppressor, fire selector, magazine catch, bolt catch, ejection port cover and rear suspension plate are made of steel. And then protected against corrosion.

Gearbox and its interior are another advantage of this replica.
It has a quick spring change system and the spring guide, as well as the piston head, had bearings. Polymer piston is equipped with steel teeth that work with high-quality gears. Gears are mounted on slide bearings to be able to cope with the highest loads. Only the motor rack is mounted on ball bearings to ensure that it is free to spin at high speeds.

Inside we will find electric trigger "Micro Switch " that is connected to the low-resistance wiring, preparing the replica for cooperation with Li-Po batteries.
The use of an electric trigger eliminates the problem of burned out contacts and improves the response to the trigger.
The gearbox's finished with aluminium, sealed nozzle. It works with a rotary metal hop-up chamber in which a hardened 6.02mm precision steel barrel is mounted.
