The SALz was developed between 2022 and 2024 as a high-performance HPA foam dart blaster based on the airsoft M4 platform. It is compatible with standard airsoft M4 grips, handguards, stocks, and most other accessories—offering virtually unlimited customization options for each build.

 Think of it as the universal receiver for HPA foam dart blasting. 

The trigger system uses an electronic valve for consistent velocity and a crisp, responsive feel. Designed with a preference for hair triggers, it features an optional tuning screw and a compact 1A limit switch. When properly adjusted, it functions as a true hair trigger.

Additional features include:

  • Quick-detach upper and lower receivers via Lynx-style pins • Fast core removal for easy maintenance
  • Simple, tuning-friendly internal layout

 

                                          Assembly instructions are included in the file set

 

                           Feel free to buy me a coffee if you end up enjoying this blaster

Notes to Builders:

- Apologies for any unclarity in the instructions… some interpretation & common sense will be required when routing cables and tubing

- In case of issues, please reach out via Discord to ironz_89

 - Some testers have reported that the mag release works better with the SuperCore when mirrored. You can do that in the STEP files included in this file set if you feel the same way.

- The instructions say otherwise, but I recommend installing the super/sniper core before closing the two halves of the lower receiver.
