Gas Airsoft Gun Instructions and Manual - Nation's Largest Airsoft Gun Retailer

These are general guidelines or instructions for Gas Airsoft Guns (pistols only). For instructions of various airsoft guns.

How to use a gas gun:

Make sure the can is ALSO upside down. Make sure they are both perfectly in line and completely vertical. Do not tilt sideways at all or angle the green gas canister and the gun magazine. Make sure the nozzles get a firm seal, and proceed to fill the "Liquid" into the mag by pressing firmly down with the airsoft gas canister. Filling time depends on the mag capacity. A normal handgun mag is generally about 3 seconds. A 50-round mag is usually about 5-6 seconds. This will insure you get a full charge of gas, for the amount of BBs.

After loading the green gas into the magazine, load the BB's. Simply pull down on the magazine follower and insert BB's as illustrated below

What NOT TO DO when filling the mag:
If you fill the mag, and gas begins to spill, STOP. Let the magazine warm up at room temperature before attempting again. This is usually about 5-6 minutes. If you are able to form a tight seal and fill correctly, allow the magazine to warm to room temperature. Tapping the big metal button on the top, rear side of the mag will discharge the GAS from the gun magazine. Do NOT do this! It will prematurely wear out the seals and also cause the O-rings to freeze, damaging them permanently. Instead, fire the gun until out of gas. This is the safe way to discharge a gas-gun.

Fire the gun in WARM weather. Using during the cold seasons are not advised. They will not cycle completely, fire well, and will use more gas than normal. Rapid-firing of the gas-gun will also cause the gun to freeze up, resulting in damage to the magazine or gun. These problems are not as prone during the hotter seasons or warmer weather.

Use HIGH grade BBs for your guns. Lower quality BBs will tend to jam in the magazine well, preventing proper firing. Marui, Excel, Airsoft Elite, or AirSplat BBs are are highly recommended. These are all models which we carry, Airsoft BB. Using .12 is not advised for higher end airsoft guns, such as electric or gas will VOID THE WARRANTY and may cause permanent damage.

Gas-gun care: Be sure to keep your slide and all moving parts lubricated with SILICONE oil which can be purchased on our website or at your local hardware store. Do not use anything else, such as petroleum based lubricants. ONLY 100% pure silicone oil is required. Other lubricants are not safe for use on plastic and rubber parts.
Do not use Hoppes #9, WD-40, and other petroleum based lubricants will damage the guns permanently.

Be sure to also spray silicone oil into the top nozzle of the magazine well every 5-6 magazines uses. This is done, by pressing the top release valve on the the mag while putting a quick spray of silicone into the top rubber exhaust valve. This will keep the seals and O-Rings properly lubed for a lifetime of use. For more details illustrations on how to maintain your gun, please refer to our Maintenance Guide.
