What Is a PCP Air Rifle? A Plain-English Guide for First-Time Buyers
Last updated November 2026 · By the Northtac Team
PCP stands for precharged pneumatic. It's an air rifle that runs on a cylinder of high-pressure air you fill ahead of time, a bit like a scuba tank built into the gun.
If you've only shot a BB gun or a break-barrel before, a PCP works differently and needs a little more gear. This page covers how one works, how it compares to the other kinds of air rifles and what you'll need before you can shoot it.
How a PCP air rifle works
The air cylinder on a PCP holds air at roughly 200 to 310 bar, or about 3,000 to 4,500 PSI. You cock the rifle with a side lever or bolt, which loads a pellet from the magazine and sets a spring-loaded hammer.
When you pull the trigger, the hammer strikes a valve. The valve opens for a split second and lets a small, measured burst of air push the pellet down the barrel. Then it closes, and you're ready for the next shot.
Many PCPs also have a regulator. It sits between the cylinder and the valve and feeds the same pressure to every shot, even as the cylinder slowly empties. That keeps your pellets landing in the same place from the first shot of a fill to the last.
PCP vs springer vs CO2
Spring-piston rifles, often called springers or break-barrels, have a spring you compress every time you cock the gun. They need nothing else to shoot, which is their big advantage. The trade-off is one shot per cocking stroke and a forward and backward jolt when the spring fires, which takes practice to shoot well.
CO2 guns run on small gas cartridges. They're cheap to get into and easy to use. CO2 pressure changes with temperature, though, so power drops on a cold day, and most CO2 rifles are fairly low powered.
PCPs give you multi-shot magazines, more power, almost no recoil and, on regulated rifles, very consistent shots. They're also quieter than most springers. What you give up is simplicity, because you need a way to fill the cylinder.

What you need to shoot a PCP
A way to fill it. A hand pump is the cheapest option and works anywhere, but it takes some effort. A scuba or carbon fiber tank fills quickly and needs refilling at a dive shop or with a compressor. A high-pressure compressor does the work for you at home. Most new owners start with a pump, like our Bintac 4500 PSI hand pump ($129.99), which fills to 310 bar.
The right fill probe. This connects the pump or tank to the rifle. Most rifles include one in the box, and our QILIN BP-C ships with a fill probe, two magazines and an O-ring kit.
Pellets in the right caliber. A tin of .22 pellets runs about $17 to $20. Buy two or three weights and see what groups best. Our pellets vs slugs guide covers how to test them.
Sights. Most PCPs don't come with sights. A basic 3-9x scope covers backyard and small-game distances.
A safe backstop and eye protection. A PCP can send a pellet a long way. Shoot into something that stops it, and wear shooting glasses.
When a PCP makes sense as a first air rifle
A PCP makes sense if you plan to shoot often, want enough power for small game or pests, or want a rifle that's easy to shoot accurately.
If you'll only plink a few times a year, a springer may be the better buy. You'll skip the cost of fill gear, and there's less to learn.

PCP air rifle FAQ
How much does it cost to get started with a PCP?
Plan on the rifle plus about $150 to $250 in extras. As an example, a QILIN BP-C ($399), a hand pump ($129.99) and a tin of pellets come to a little over $540 before a scope. The QILIN BP-C is on pre-order right now, and you can cancel a pre-order for a full refund any time before it ships.
Do I need a license to buy a PCP air rifle?
Not under federal law, and there's no FFL transfer. You need to be 18 or older to buy one from us, and some states and cities add their own rules. Our guide to shipping an air rifle lists where we can and can't send one.
How many shots do I get from one fill?
It depends on the caliber, the power setting and the size of the cylinder. Check the shot count listed for your rifle and treat it as a starting point, since your pellets and tune will move it up or down.
