You will have to take it apart. Each model is different so you will have to find a diagram of the rifle.

How do change the air cannon in a BB gun?
Because of the small design of a BB gun it is not possible to change the air system. However if it's a pellet springer rifle, not a BB rifle, then in some cases it is possible to change it with a Nitro piston system. But this should be done by a professional air gun service. A nitro system replaces the spring piston with a gas piston tube. It usually cost around $130.
How does a nitro piston air rifle work?
When you cock the rifle it compresses the gas behind a piston just like a spring. Basically it replaces the spring.
How does a spring air rifle work?
When the rifle is cocked, a spring is compressed. Pulling the trigger releases the spring, which pushes a piston forward, The piston compresses air as it moves. The compressed air blows the BB or pellet out of the barrel.
How does a spring rifle work?
spring drives a piston that pushes air
What is a spring powered air rifle?
A spring powered system uses a spring that is inside an air tube. The spring is attached to a piston. When the rifle is cocked the spring and piston are drawn back and locked at one end of the air tube. The other end of the air tube has a small hole that is directly behind the pellet and rifle barrel. When the trigger is pulled the spring is released and it pushes the piston down the air tube forcing all the air through the hole, and that fires the pellet down the barrel.
What is a spring-powered air rifle?
Their are 4 common types of air rifle power plants. Spring power: or Nitrogen piston power. this uses a large spring inside an air piston tube; When the barrel is cocked (Commonly called a break barrel rifle) the spring is pushed back in the piston chamber and locks. A pellet or BB is loaded. When the trigger is pulled it releases the spring, forcing the piston forward in the air piston chamber, Compressed air fires the pellet out the barrel. C02: a C02 cartridge is loaded into the rifle and acts as a small air chamber releasing some C02 each time the trigger is fired. Eventually the C02 is used up and has to be replaced. Pump power. simply you pump the forearm on the rifle and it fills an air tank. When you have enough compressed air you fire the rifle PCP: Pre Charge Pneumatic: This is a large air tank inside the rifle. It is charged with a bicycle pump or scuba tank. It's like an oversized C02 tank inside the rifle. Again each time the trigger is pulled the tank releases a burst of air behind the pellet to fire it out of the barrel. This type of air rifle is usually a very high-powered rifle.
Does a pellet have to be in the chamber for a Crosman 140 to fire?
The rifle will fire without a pellet, but over time it will ruin the air chamber and air piston inside the chamber. When you pull the trigger the air piston slides forward inside the air chamber compressing the air behind the pellet. At the last moment it actually slows down as the pressure builds and fires the pellet. Without a pellet in the loading port the piston has no resistance and just slams against the stop. This will eventually ruin the rifle.
What oil can you use in the spring piston of an air rifle?
Pellgun oil by Crosman. Do not use anything else. It will ruin the seals.
What will happen to a pellet gun if you dryfire it?
Most spring Pellet guns should not be dry-fired. When you shoot a spring powered air gun or rifle, the spring compresses the air in the airtube and the compressed air forces the pellet out of the barrel. The compressed air also slows down the spring piston due to the air being compressed. In this way the piston doesn't slam against the end of the chamber. When you dry-fire the rifle without a pellet in the breech the piston has no resistance in the chamber and slams against the end of the airtube. Eventually it will ruin the air tube and the rifle or gun. If you dry-fire a C02 gun nothing will happen no damage will occur.
How do rifle ballistics change in a vacuum?
No air, no resistance
Is it bad to dry fire an air pistol?
It's OKAY to dry fire a C02 pistol but do not dry fire a spring or pump pistol or rifle. When the piston in a spring pistol compresses the air inside the chamber to fire the pellet is actually slows down as it decompresses the spring piston just before it fires the pellet out of the chamber. This slowing down Keeps the piston from slamming against the end of the chamber and ruining it. When there is no pellet in the chamber the piston has no resistance and slams against the end of the chamber. This will eventually destroy the piston and the air chamber.
How do you make an air rifle more powerful?
There are several air rifle shops around the country that (TUNE) air rifles. Check the web under" air gun repair" or "air gun tune" and locate a shop near you to have the modification done. Also Pyramyd Air (see the link below) sells a NITRO Piston to replace the spring in most air rifles.
