Description
Swiss Arms Gas – 150 PSI – Scar Heavy Gas (Silicone – 760ml – 603514)
Swiss Arms Scar Heavy Gas is a 150 PSI airsoft gas from Cybergun’s Swiss Arms range, supplied in a 760ml can (reference 603514). It is a higher-pressure gas, intended for gas blowback rifles and other replicas built to run on stronger gas, such as SCAR-pattern GBB rifles with heavier bolts to move on every shot.
This version contains silicone, so a little lubricant goes into the magazine with each fill. That helps keep valve and magazine seals supple between full services, which is useful if you use your gas rifle regularly. The large can makes it good value for GBB rifle owners, who tend to get through gas far faster than pistol users.
Why choose heavy gas?
Gas rifles need enough pressure to cycle a long, heavy bolt carrier reliably, and pressure drops as the gas cools during rapid shooting or on a cold day. A 150 PSI gas gives more headroom than standard green gas, helping the rifle keep cycling with consistent power. The retailer guidance for this can is that it works best above 15 degrees, so in cold weather keep your magazines warm before use.
Filling magazines
Hold the can upside down and press the nozzle squarely onto the magazine’s fill valve in short bursts until it stops taking gas. Do not overfill. Let the magazine settle for a moment before inserting it, and wipe away any excess silicone around the valve.
Key features
- 150 PSI heavy gas
- 760ml can
- Contains silicone to help lubricate seals
- Intended for SCAR-type and other gas rifles rated for higher pressure
- Best used above 15 degrees
- Swiss Arms / Cybergun reference 603514
Compatibility
Only use in replicas that the manufacturer rates for higher-pressure gas. Many gas pistols, and some rifles, are designed for lower-pressure gas, and running them on 150 PSI gas can crack slides or wear parts early. Check your replica’s manual before use.
Care and maintenance
Store the can in a cool place away from direct sunlight and heat sources, and never puncture or burn it, even when empty. Store your magazines with a little gas in them to keep the seals seated.
Who is it for?
GBB rifle owners, particularly with SCAR-type and other heavy-bolt rifles, who want a lubricated high-pressure gas in a good-value can.
Please note: Pressurised container. Keep away from heat and flames, and use in a well-ventilated area.
