The new ETU series from Delta Armory called Fully upgraded - No compromises is characterized by a complete upgrade and almost an ETU unit (Electronic Trigger Unit).


Upgrade parts:

  • CNC 16:1 gears
  • CNC Piston head
  • CNC Nozzle
  • CNC Stainless steel cylinder
  • CNC Stainless steel spring guide
  • High Torque motor with strong neodymium magnets
  • Full metal teeth piston
  • Precison 6,03mm barrel
  • ETU unit with functions:

  • Pre-cocking -spring preload - faster response when pressing the trigger

  • 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 - the possibility of setting the shooting with a triple dose


Thanks to the processor, the ETU response has a cadence and the trigger 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 connector.


Thanks to the high-quality internal parts, we recommend using 11.1V LiPo batteries.

The actual measured FPS of this model is: 396,6 FPS with 0.20g BB.


The CHARLIE series is 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 weapon. The weapon also has a unique serial number. The stock is much better handled than other brands in a similar price category, and inserting the battery is much more convenient. There are 22 mm RIS rails on the weapon, on which it is possible to attach various accessories. The weapon has an adjustable rear sight, mounted on a RIS rail. The barrel is finished with a 14 mm left-hand thread. The weapon has a silencer mounted on the barrel. 


Package includes weapon, M4 DMAG Mid-Cap 130BB magazine, Keymod tactical grip. 

Battery and charger are not included in the package.
