HPA / Air Tank and gun not included.The Redline Airsoft AirStock (patent pending) allows you to ditch your remote hose and mount a tank directly to your gun.
Intended for use with a 13cu air tank that, depending on your setup, gets from 700 to 900 shots per fill.
The AirStock balances nicely on an average M4 and since the AirStock comes complete with a Firebase regulator, performance is not an issue.
The kit comes with all the hoses, bolts and fittings required for installation on both VFC and non-VFC bodied guns.


  • High quality steel and aluminum construction
  • Alternate way of mounting an HPA tank directly to your gun
  • Integrated sling loops
  • Redline Firebase Regulator installed
  • Safely and easily regulates pressure from HPA Tank to Gun
  • Hoses, fittings, and bolts necessary for installation included
Compatibility: PolarStar PR-15, Fusion Engine.

Disclaimer: The AirStock is designed for use with either a Ninja 13cu SLP HPA tank, or a Guerrilla Air 13cu ELP tank only! Use of tanks with an output pressure greater than 300 PSI will result in damage!
