These Nuprol 12g CO2 gas bulbs can be used for both Airsoft and Air rifles and are great for year round use.
Manufactured to the highest standards with an integral silicone lubricant (similar to that in green-gas), Nuprol Co2 helps preserve your airsoft gun’s seals and reduce the general wear and tear on your weapon by lubricating the seals, values and any moving parts the gas comes into contact with. This results in a drastic reduction in the amount of manual maintenance that you would need to carry out on the weapon.
This cartridge provides you with a snug fit and solid seal for a reliable, consistent performance in almost any Co2 pistol or rifle.
