Crosman has parts for this rifle. You will find their 800 number at the bottom of the attached document. The Storm XT is model C1K773932. See the link below. BTW it's an Air Rifle not an Air Gun.

spring drives a piston that pushes air
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.
Not usually. There are several factors involved besides the spring, but the .22 will usually use a stronger spring to propel the heavier pellet.
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.
When you cock the rifle it compresses the gas behind a piston just like a spring. Basically it replaces the spring.
The Shamal was not Air Arms first spring rifleIt was their first pre-charged air rifle and a very good oneValue greatly depends on condition, type of stock and to whether the rifle is regulated or notHence value range £180 to £400
Not recommended. Not desgined for a more powerful spring.
Yes it can but getting the current rifle "Tuned" by an expert will get you better results. Tuning will make the spring and trigger perform better.
Contact the maker to see if it is possible and what it will cost.
It all depends on the Rifle and bipod model.
