How does a perfect seal and no tappet plate or return spring sound?


Well to Aztech Innovations it sounded pretty dam amazing.  So they designed and built it. A tappet less cylinder head that works!!

Here it is, the APACHE!  The first of its kind in the world, all air controlled driven by the piston. 

  • No mechanical forks or prongs to retract the nozzles
  • No timing issues
  • No broken return springs
  • No broken tappet plates and best of all no fps droop on high rate of fire.


The all in one sealed cylinder head ensures perfect seal for max air flow and zero air loss with out any mechanical gear driven parts to create issues.


The APACHE produces extremely consistent high pressure air flow seen as a huge improvement in consistency of feet per second plus a noticeable improvement in accuracy thanks to reduced turbulence of the airflow through the tri port and past the aerodynamic "boat tail'' internal nozzle, combined these streamline the airflow into the barrel and behind the gel, pushing the gel in a single uniform flow for max power.


Please note, using an APACHE DOES NOT increase the volume of your cylinder.  The APACHE doesn't open be able to increase volume, it opens when cylinder pressure increases through the piston moving forward, then the air moves from the Cylinder forward into the APACHE, the volume doesn't increase as it opens it moves.

To prevent risking damaging the APACHE nozzle we suggest do not fire the Apache with the upper receiver off. 



  • No timing issues... ever!
  • Improved accuracy!
  • Max efficiency, max range, less turbulent flight.
  • Unique sound - everyone will know you are running an APACHE
  • No more broken return springs
  • No FPS loss from semi to auto modes
  • Adjustable nozzle length (4mm of adjustment) using spacers
  • Tappet plate and return spring no longer required
  • Includes less strong 0.8mm internal spring, 2mm and 3mm sorbo pads


Tested and proven to feed perfectly with zero fps drop comparing semi auto to full auto all the way up to 85 rps on DSG and well over 500 fps on SSG.

The APACHE is a hi tech little piece of kit, we highly recommend only experienced AEG builders tackle an install and setup. The theory is very similar to HPA for tuning and airflow.  The process is definitely made easier with the Aztech Adjustable T piece to assist in setting the seal of the nozzle to the t piece while allowing for perfect feeding from the magazine. 


APACHE comes with 2 springs, the 0.9mm spring is installed from new, you may need to change this to the spare 0.8mm spring in the box.


We recommend only using Ausgel Elite or AKA Extra Hard gels, softer gels and older gels will not be able to handle the high nozzle speed of the APACHE. 

We also recommend a low strength loctite on the cap thread when you finally install it to ensure the top cap does not unscrew under high vibration environment.
