The difference between PCP and gas cylinder systems in the air force
When choosing an airgun, one of the most important decisions is whether to go with PCP (Pre-Charged Pneumatic) or gas cylinder systems such as IGT (Inert Gas Technology) and Nitro Piston. Both systems have their advantages and disadvantages, and the right choice depends on your needs, usage scenario, and preference. In this guide, we'll go over the differences between the two technologies, how they work, and what you need to consider before choosing your airgun.
What is PCP (Pre-Charged Pneumatic)?
PCP is one of the most popular technologies in airguns and is used especially by experienced shooters and competitive shooters. PCP airguns use compressed air stored in a pressurized tank in the gun, which provides multiple shots with consistent power.
How does PCP work?
-
Air is filled into the weapon's pressure tank via a manual pump, diving cylinder, or high-pressure compressor .
-
When the trigger is pulled, a small amount of air is released, propelling the shot out of the barrel.
-
Many PCP guns are regulated , meaning that the pressure is delivered in a steady amount for each shot, increasing precision.
Advantages of PCP systems:
✅ High precision and consistent shots – Constant pressure means minimal variation in shot power.
✅ High capacity – Can fire multiple shots per load (typically between 30-100 shots depending on the weapon).
✅ Low recoil – No spring movement provides more stable shooting.
✅ High power capability – PCP guns can fire with higher energy than other systems.
Disadvantages of PCP systems:
❌ Requires a filling station – You will need a compressor, pump or pressure bottle to fill the tank.
❌ More expensive initial cost – PCP guns are often more expensive than spring and gas cylinder systems.
❌ More maintenance – Pressurized systems can have leaks and require regular inspection.
What are gas cylinder systems (IGT, Nitro Piston, etc.)?
Gas cylinder systems are a newer technology that replaces the traditional spring-operated systems. Instead of a spring, these weapons use a sealed gas cylinder that creates pressure to fire the shotgun.
How do gas cylinder systems work?
-
When you charge the weapon, you compress a gas-filled cylinder .
-
When the trigger is pulled, the stored energy is released, propelling the shot forward.
-
The system provides a smoother force curve than traditional spring systems.
Advantages of gas cylinder systems:
✅ More durable than spring systems – No mechanical springs that can wear out over time.
✅ Less recoil – Provides smoother shooting compared to traditional spring-powered weapons.
✅ Less temperature sensitive – Unlike CO2-powered systems, gas cylinders are not significantly affected by cold.
✅ Faster reloading – Less vibration makes it easier to regain target after shooting.
Disadvantages of gas cylinder systems:
❌ Less consistent than PCP – There may be slight variations in shot power over time. ❌ Lower shot capacity – Each shot requires manual loading, so you only get one shot at a time.
❌ Not as powerful as PCP – Limited to mid-range energy levels.
Which system suits you best?
| Function | PCP | Gas cylinder (IGT/Nitro Piston) |
|---|---|---|
| Precision | High precision, consistent shots | Moderate precision, less uniform |
| Recoil | No recoil | Low recoil |
| Capacity | 30-100 shots per charge | One shot at a time |
| Maintenance | Requires pressure monitoring | Minimal maintenance |
| Price | More expensive | Cheaper |
| Power supply | Requires air compressor or pump | No external supply required |
| Best for | Sport shooting, hunting, long distance | All-round shooting, durability |
Conclusion
The choice between PCP and gas cylinder systems depends on your needs:
-
Choose PCP if you want the best precision, high capacity and consistent shots.
-
Choose gas cylinder (IGT/Nitro Piston) if you want a simple, durable and maintenance-free weapon.
Both technologies have their place in the air force world, and the right choice depends on your usage situation and budget.
