The SpeedQB AtomPacK (APK) is a modular, multi-configuration backpack designed for airsofters who run HPA (High Pressure Air) systems. Ergonomically designed to move with your body, not against it. The APK comes with everything you need to deploy in 3 different modes:


Chest Rig Mode

  • The APK can be connected to the Nucleus Chest Rig to create a HPA carry + Ammo Retention system.  
  • Nucleus Chest Rig is NOT included with APK. Sold separately.


Standalone Backpack Mode 

  • StandAlone mode allows the APK to be deployed as a traditional backpack with 2 shoulder straps, and an adjustable chest H-strap.  


Crossbody Bandolier Mode 

  • The APK can also be worn as a Crossbody Bandolier pack. This configuration offers a dynamic carry solution for HPA systems on the field and doubles as an ergonomic, crossbody bag, off the field.


AtomPacK Features:

  • Structured and Padded throughout to protect your HPA Tank from field elements
  • Airmesh Padding offers breathable ventilation and sweat wicking properties 
  • “MagStash” Pocket (fits 2 Single AR PMP or 3 single pistol PMP)
