CM605 M4 Carbine

A series of American assault rifle replicas manufactured by CYMA. The replica is characteristic for its beneficial quality to price ratio known from previous products from the company.

Replicas were made fully compatible with the Tokio Marui standard and equipped with metal Hop-Up chambers as well as M120 springs that guarantee a muzzle velocity of ~405 FPS, which makes them a highly-effective tool for medium-range operations.

Particular elements of the replica were made in a way facilitating a good alignment of internal parts as well as the appropriate placement of electronic and mechanical parts of the internal construction.

The replica was made of metal and polymer. Polymer parts include: the receiver, front RIS, foldable stock and the pistol grip. Metal parts include: the barrel, magazine and remaining, miscellaneous parts of the replica. The implementation of a metal gearbox in the replica significantly prolongs its operation time rather than in the case of the use of parts made entirely of polymer. Thanks to the metal gearbox the replica can be subjected to numerous alterations that aim to improve its reliability as well as power.

The implementation of a foldable stock enables the adaptation of the replica practically to any User and its usage in various situations and conditions. The top RIS rail enables a seamless attachment of a red dot sight or a scope.

The carbine features an adjustable Hop-Up system that can be accessed by pulling back the charging handle, which opens the shell ejection window flap, revealing the adjustment knob.
