Airsoft rifle M4 AR15 SilentOps 7" Charlie ETU - Black
Delta Armory's ETU series, Fully upgraded - No compromise, features a complete upgrade and the addition of an ETU (Electronic Trigger Unit).
Upgrade parts
- CNC 16:1 gears
- CNC piston head
- CNC cylinder head
- CNC nozzle
- CNC stainless steel cylinder
- CNC stainless spring guide
- high torque motor
- piston with metal teeth

ETU processor features
- Pre-cocking - precompressed spring - faster trigger pull response
- Binary trigger - double shot - when the trigger is pressed the gun fires once and when the trigger is released it fires a second time
- Burst mode - triple shot setting
And of course, thanks to the ETU processor, the gun has a high rate of fire (ROF) and the trigger response is much better than with conventional mechanical trigger contacts.
At the same time ETU series is equipped with Deans T connector, which replaced Mini Tamiya.
Due to the high quality internal parts, we recommend using 11.1V LiPo batteries. For example, an 11.1V LiPo 1100 mAh battery or another battery with approximate dimensions: 1.4 x 1.9 x 10 cm.
Real measured muzzle speed of this model is: 121 m/s (398 FPS) with 0.20 g BB.
The CHARLIE series is mainly characterized by high quality internal parts. The gun is made of durable ABS polymer. The trigger is CNC Type A which speeds up the reaction time of the gun.
The gun also has a unique serial number. The stock is much better designed than other brands in a similar price range, and the battery insertion is much more comfortable. There are 22 mm RIS rails on the gun to mount various accessories. The weapon has an adjustable rear sight mounted on the RIS rail. The barrel is finished with a 14 mm CCW thread.
A silencer with damping foam is mounted on the barrel of the weapon.
Battery and charger not included.
