Delta Armory airsoft gun M4 AR15 SilentOps 7" Charlie ETU Black
DA-C05-ETU

The ETU series from Delta Armory, called Fully upgraded - No compromise, features a complete upgrade and the addition of the ETU unit (Electronic Trigger Unit).

Upgrade parts:

CNC 16:1 wheels
CNC Piston Head
CNC cylinder head
CNC Nozzle
CNC Stainless steel cylinder
CNC Stainless steel spring mandrel
High Torque motor
Piston with all-metal gearing
Precision 6.03mm barrel

ETU processor features:

Pre-cocking - spring preload - faster trigger pull response
Binary trigger - double shot - when the trigger is squeezed the gun fires once and when the trigger is released it fires a second time
Burst mode - possibility to set triple burst firing

And of course, thanks to the ETU processor, the gun has a fast cadence and the trigger response is much better than with classic mechanical trigger contacts.

At the same time, the ETU series is equipped with a Deans T connector, which replaced the small tamiya.

Due to the high quality internal parts, we recommend using 11.1V LiPo batteries. For example, 11.1V LiPo 1100mAh battery or other battery with approximate dimensions: 1.4 x 1.9 x 10 cm.

The real measured FPS of this model is : 396,6 FPS with 0,20g BB.

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, on which various accessories can be mounted. There is an adjustable rear sight, mounted on the RIS rail. The barrel is finished with a 14 mm left-hand thread. A silencer with damping foam is mounted on the barrel of the weapon.
