Redline Airsoft

Add to wishlist

The patented Redline Airsoft AirStock allows you to ditch your remote hose and mount a tank directly to your gun!

Intended for use with a 13cu air tank air tank that, depending on your setup, gets from 700 to 900 shots per tank.

The AirStock balances nicely on an average M4 and the kit comes with all parts required for installation on both VFC and non-VFC bodied guns.


Air tank and gun not included.

Installation requires routing the engine air line to the rear. Some modification of the gearbox shell is required.

(Not recommended for use with Polarstar Fusion Engines)


The AirStock is designed for use with either a Ninja 13cu SLP HPA tank, or a Guerrilla Air 13cu ELP low-pressure air tanks. Use of air tanks with an output pressure greater than 300 psi is not recommended.
