Every model is different. Some require more pumps than others. Some only require one pump.
A person can make the pump easier to operate on a Crosman 760 air rifle by applying oil to the seals. This will provide lubrication and improve the overall action of the weapon.
If you are asking about the 2200 Crosman Magnum air rifle then it shoots a .22 caliber pellet not a BB.
Because a self loading rifle relies on the power of the explosion expelling the bullet to push back the bolt and load another bullet. With a pump action air rifle there is not enough power to both shoot the pellet and push back the bolt, therefore it uses all the pressure to expell the pellet.
From 1990-1996 Daisy made the model 990 that was multi-pump and C02.
pump-charged gun
A pump action BB gun requires you to pump the forearm (The grip under the barrel) several times to store air in the air tube. This air propels the pellet when the trigger is pulled.
In order to give you an estimate of value you will have to state the model number and the current condition of the rifle. Does it still hold air? Is it in poor, fair, good, very good or excellent condition?
The Daisy model 880 and the Crosman 760 are both Variable pump rifles. To charge the rifle you must pump the forearm from 1 to 10 times to store enough air to fire the pellet or BB. With each pump you store a little more air in the air cylinder and increase the power of the rifle when it is fired. It takes a minimum of 2 pumps to store enough energy/air to make the BB or Pellet fire. Never pump the rifle more than 10 times or it may rupture the seals.
What Model? What condition? Excellent, good, OK, Fair, Poor. Does it still work? Does it still hold air? You need to answer these first to get a realistic estimate of Value!
Yes. Pellet guns are: Pump action, C02 driven, Spring action. The more powerful ones are called PCP. (Precharged pneumatic. ) They use a Tire pump or scuba tank to charge them. All Air Guns & Air Rifles are driven by Air or C02.
You will have to provide the caliber and whether it is pump or CO2 powered.
It all depends on who made the air rifle and the power plant that the rifle uses.
