The latest tappetless system available and takes our APACHE to a new level!

Here it is after numerous prototypes of a new design, the APACHE PRIME!  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 bb, pushing the bb 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
  • Tappet plate and return spring no longer required

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. 

You will need to unscrew the base and glue on an included spacer that will stop double feeding. You no longer have to adjust the nozzle to get a perfect seal, the APACHE will automatically do that but you need to insert and glue in a spacer that stops double feeding.

This APACHE comes with the included spring only, no different type is needed. We also recommend a low strength loctite on the bottom base thread when you finally install it to ensure it does not unscrew under high vibration environment.

  • The body is made completely of 7075 CNC aluminum
  • Nozzle made from CNC 7075 Aluminum
  • All seals are Nitrile 70 duro rubber.
  • Anodized black and red
  • 3 spacers included in the box being 1.5mm, 2mm and 2.5mm thick to eliminate double feeding
