No
Well Yes and No. Let me explain. In the USA there is no limit on The power of an air rifle so a strong spring is used. In other countries, like Canada, there is a limit on the power an air rifle, so a different spring is used that produces less power. Normally you do not want to tamper with the design of an air rifle because it could cause damage to other parts of the rifle that may not be able to handle the change in design.
Their are several ways to increase the power of and Air Rifle. But you will need the right tools. Polishing the air chamber will help. Remove any burrs in the slide action will help. using lighter pellets will increase the speed but not the power. Never use regular oil on an ait gun only use pellgun oil. Regular oil will eventually ruin the seals. A bigger spring will help, but make sure you rifle can handle the modification. Their are several airgun shops on the web that can modify or tune up an airgun. Check under "Airgun repair" or "Airgunsmith" on the web and you will find several.
Please state the model you are inquiring about. Is this a C02 or a PCP (Precharged Pneumatic) air rifle?
No such rifle
Yes Diana RWS rifles are still made. See the link below.
no
Add a few drops of Crosman Pellgun oil to your pellets.
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.
spring drives a piston that pushes air
Nitro has a few advantages over Spring. You can leave it cocked for a long period of time and not worry that it will loose it 's power. You have a more even release force with nitro ( A spring wobbles). There is not a spring to break or get soft over time. The power will always be consistent.
BB guns have 3 different power plants. Spring, C02 and Pump. 1. Spring power: When the rifle or gun is cocked a spring is compressed inside a piston and released when the trigger is pulled. The piston pushes air ahead of it forcing the BB to fly out the barrel. 2. C02: C02 gas is contained in a cylinder. when the trigger is pulled a burst of C02 gas is released and forces the BB out the barre 3. Pump: When the rifle is pumped using the forearm, air is stored in a cylinder inside the rifle. when the trigger is pulled the air is released forcing the BB out the barrel. There is one more power plant but it is used in High power air rifles and guns only and that's PCP. Air is introduced into the rifle with a scuba tank taking the pressure up to 3000 PSI and is used to power the rifle for several shots.
