At Abbey Supply, we sell 5 different kinds of airsoft gases, not to mention the different kinds sold by other companies. With that many different products on the market which (on the face of it) do the same thing, it’s difficult to tell which airsoft gas is the best for your needs. So, in this article we’re going to clear that up for you and tell you which Abbey gas is the best for which scenario.
Which gas you should use depends greatly on 2 different factors, which kind of weapon it is (namely, the material of the moving parts) and the temperature outside.
Plastic Slides and Bolts
Weapons with plastic parts, such as pistols from Tokyo Marui (plastic slide) need a weaker gas. The slide is lightweight, so an acceptable FPS can be gained with a weaker gas and the slide is weaker, so a more powerful gas will eventually crack and break the slide. Our gas for these purposes is Abbey Predator Gun Gas 144a.
Metal Slides and Bolts
Metal pistols have a heavier more durable slide and the bolt inside GBBRs is usually a hard metal. They’re often designed to take a bit of a beating and if properly lubricated and cleaned (view our guide here), they’ll last a life-time. Due to the fact that the heavier slide/bolt requires more energy to pull back, we recommend a more powerful gas. This helps keep your fps high enough and your cycle rate crisp. For this we recommend Abbey Predator ultra, although in colder weather, you may want to jump to Abbey Predator Vertex Gas.
Warm weather increases the pressure of the gas in its container. This increases the FPS of the weapon and increases the internal stresses. If your gas gun is close to the FPS limits on a standard temperature day, you may find that the same gas puts you over the limit. This is when you should use a slightly lower pressure gas. For rifles which usually use Abbey Predator Vertex Gas, you may want to drop down to Abbey Predator Ultra.
A gas which you may not be aware of is one used for storage. When your magazine is in storage, the o-rings in the valves and seals may potentially dry out and crack, meaning they’ll no longer keep their seal. For this, we introduced Abbey Maintenance Gas. It’s formulated with extra lubricant to keep those o-rings and seals fresh. Do not use this gas for skirmishing or shooting.
