What’s Best in the UK?
If you own a PCP air rifle, the first thing you quickly realise is that compressed air is part of the deal. Unlike spring airguns, a PCP system relies entirely on high-pressure air stored in a cylinder. That air has to come from somewhere.
In the UK, there are three main ways to charge PCP air rifles: a hand pump, air bottles (pcp air tanks), or a compressor. Each system has advantages and drawbacks depending on budget, location, and how much shooting you actually do. This guide breaks down cost, portability, maintenance, and real-world ownership so you can decide what’s the best option for you.
Why Charging Matters for PCP Air Rifles
PCP air rifles store compressed air inside a cylinder or air tank, typically filled to 200–300 bar. That stored air powers every shot. Once pressure drops below a certain point, performance falls away.
Consistent, clean, dry air is essential. Moisture inside the system can damage valves and internal components over time. That’s why how you fill your PCP matters just as much as the rifle itself.
Option One: Hand Pumps
A hand pump is the most affordable way to charge a PCP air gun. It’s compact, portable, and doesn’t require electricity.
For occasional shooters, a pump can be a practical starting point. You can refill your cylinder at home without relying on a dive shop or external source.
Pros of a Hand Pump
- The biggest advantage is cost. A pump is far cheaper than compressors or air tanks. It’s also easy to store and carry.
- For shooters who fire modest shot counts, pumping is manageable. It gives you complete independence.
Cons of a Hand Pump
- Manual pumping requires effort. Filling a large cylinder from empty can be hard work. Over time, that effort becomes noticeable.
- Heat and moisture are also concerns. Without a good filter system, moisture can enter the air path. That can affect internal valves and seals.
- For high-volume shooters, pumping quickly becomes tedious.
Option Two: Bottles and PCP Air Tanks
Using bottles or PCP air tanks is extremely common in the UK. These air tanks are typically filled at a dive shop and used to recharge your rifle at home.
An airgun air tank stores high-pressure air, usually 232 or 300 bar, and can refill your rifle many times before needing a refill. PCP air tanks are portable and can fill to 4500 psi, allowing for multiple refills before needing to be filled themselves. Using a PCP air tank is more convenient than using a hand pump, as it allows for quicker and easier refills of airguns.
There are three main types of PCP air tanks: industrial static tanks, scuba tanks, and carbon fibre tanks. When it comes to refilling a PCP air tank, you have several options, including manual pumps, compressors, and portable air tanks. Using a PCP air tank as a refill option is especially advantageous for its convenience and mobility compared to other methods.
Why PCP Air Tanks Are Popular
PCP air tanks make a huge difference in convenience. Instead of pumping, you simply connect fittings, open the tank valve, and fill your rifle in seconds.
For most shooters, that ease of use is worth the initial spend. Bottles also reduce wear on your rifle’s internal components because filling is smoother and more controlled. PCP air tanks provide a supply of compressed air that can enable users to fire significantly more shots between refills compared to hand pumps.
Dive Shop Refills in the UK
Many UK shooters rely on a local dive shop to refill their tank. This is affordable and reliable. Filling a PCP air tank at a dive shop means it is filled with dry and filtered air, minimising the chance of rust inside the cylinder and reducing the likelihood of component leakage, which helps prolong the tank's lifespan.
However, access can vary. Not everyone lives close to a dive shop, and opening hours may limit flexibility. If you shoot frequently, regular refill trips become part of your routine.
Portability and Field Use
Air tanks can be transported to the range, but weight matters. Weighing PCP air tanks or cylinders is important when choosing a product, as lightweight options are advantageous for mobile use and ease of handling. A steel tank is heavier, while carbon fibre bottles are lighter but cost more. Carbon fibre tanks can handle higher pressures (up to 4500 psi) and offer better portability compared to aluminium tanks, which are generally limited to lower pressures.
For field shooting, carrying a full-size tank is rarely practical. PCP air tanks are compact and mobile, making them suitable for carrying to shooting ranges or for use in the field. Most shooters refill at home before heading out.
Option Three: Compressor Systems
A dedicated compressor has become increasingly popular among PCP owners in recent years. A quality compressor allows you to fill your rifle or air tanks at home without relying on a dive shop. When using a compressor, it is important to set the regulator on the right pressure to ensure safe and efficient filling of PCP air rifles and tanks.
- This option requires a higher upfront cost, but for regular shooters it offers long-term independence.
Benefits of Owning a Compressor
- The biggest advantage is control. You can charge your PCP cylinder whenever you want. No travel, no waiting, no refill schedule.
- Modern compressors are compact and designed specifically for airguns. Many include moisture filters and automatic cut-off features for safety.
Things to Consider
Quality matters. A cheap compressor without proper filtration can introduce moisture into your system.
You should look for a product rated for PCP use with proper dry air filtration. Protecting your rifle’s valves and seals is important over years of ownership. Features like rubber boots can protect the paint on the cylinder and prolong its lifespan.
- Noise and space are also factors. A compressor needs room and a stable power supply.
Cost Comparison: What Do You Really Spend?
Initial cost is the first thing most buyers consider.
- Hand pump: lowest cost
- PCP air tanks: mid-range investment
- Compressor: highest upfront spend
However, long-term cost changes the picture. When purchasing PCP air tanks, making an informed decision is crucial; consider both the initial price and the ongoing costs to find the best value for your needs. Over years of shooting, regular dive shop refills add up. A compressor eventually pays for itself if you shoot a lot.
For occasional shooters, a bottle is often the best option. For heavy users, a compressor becomes more attractive.
Maintenance and Reliability
Hand pumps require periodic servicing and seal replacement. They also demand physical effort every time you fill.
Air tanks require periodic inspection and testing. In the UK, tanks must meet safety standards and have valid test dates.
Compressors require maintenance too. Filters need replacing and moisture traps must be checked. A good system is reliable, but it isn’t maintenance-free. Many suppliers stock pumps, cylinders, and filling kits for maintenance and replacement needs.
Which Option Suits Different Shooters?
The Occasional Garden Shooter
If you shoot occasionally at home, a hand pump or a small PCP air tank is usually enough. You won’t be refilling constantly.
The Club or Range Regular
If you shoot weekly or fire high shot counts, bottles make life easier. Many shooters at the range rely on PCP air tanks. Range shooters can find the right tank for their needs by considering factors like shot count, portability, and available refill options.
The High-Volume Shooter
For those who shoot a lot or own multiple variants of PCP air rifles, a compressor becomes the most practical system. Many suppliers sell compressors and airgun air tanks specifically designed for high-volume shooters. It removes reliance on a dive shop and gives full control.
Safety and Pressure Considerations
High-pressure air demands respect. We recommend only buying air tanks with recognised safety certifications, such as DOT in the US or CE in Europe to ensure structural integrity and avoid uncertified or second-hand tanks. Always check fittings and rated pressure before filling.
Never exceed the rated pressure of your cylinder. Whether using bottles, pumps, or a compressor, safe practice protects both you and your equipment.
Moisture is the enemy. Dry air is essential to prevent internal damage over time.
Compatibility With Modern PCP Airguns
Modern PCP systems, including rifles from established UK manufacturers like Air Arms, are designed for safe, repeatable charging.
However, compatibility with fittings and connectors matters. Always confirm that your chosen kit matches your rifle’s filling system. Each bit of the filling process (such as connection hardware, pressure gauges, and connectors) is crucial for safe and efficient filling.
Real-World Ownership Scenarios
Many verified owner reviews show that the charging choice often changes over time. Many verified owners are happy with their chosen charging solution, citing positive reviews and satisfaction.
Shooters may start with a pump, move to bottles, and eventually invest in a compressor. Needs evolve as shooting habits change.
Your chosen solution should match how often you shoot and how much independence you want.
So, What’s the Best Option in the UK?
There isn’t one answer for everyone.
- If budget is tight and usage is light, a hand pump works.
- If you want convenience without high upfront spend, PCP air tanks are ideal.
- If you shoot regularly and want total independence, a compressor is hard to beat.
The best option depends on your shooting volume, location, and long-term plans.
Choose What's Best For You
Owning a PCP air rifle means committing to a charging system. Whether you choose a pump, bottles, or a compressor, make sure it suits your routine.
Clean, dry air protects your rifle and helps maintain consistent performance. Choose carefully, maintain your equipment, and your PCP will serve you well for years.
If you’re building your complete PCP setup, consider your charging solution as carefully as you choose your rifle. For portability and safety, store your PCP fill adaptor in a protective case. Carbon PCP air tanks are built with a strong, durable outer shell that can withstand impacts. It’s not just an accessory; it’s part of the system.
