The G&G cmf-16 is inspired by the famous HK416. The carbine is made mainly of durable polymer, including elements such as the receiver, handguard, muzzle device and the stock. Small elements of the replica were made of aluminum, while the magazine, buffer tube and the shell ejection window flap were made of steel.
The replica features two electronic systems: MOSFET (newest, 4th generation) and ETU (Electronic Trigger Unit) - that extend the replica’s lifetime and improve parameters such as the trigger reaction time or rate of fire, inform about low battery charge as well as a possible damage to the gearbox. In addition, ETU enables programming fire modes, including a 3-5 BB burst
