Yes it can but it may also damage the gun or rifle if it is too strong. If you are talking about an Air Soft gun, I would talk with an Air soft shop first. If you are talking about a BB/177 airgun, you can find information on the web. In fact www.pyramydair.com offers an upgrade kit for one of their rifles. It used an air piston instead of a spring. Also NEVER "Dry Fire" an air rifle. It slams the piston against the end of the tube without any resistance and will eventually destroy the tube. There are several air gun shops that will "Tune" and air rifle buy polishing the chamber and tweaking the spring (Remove any burrs). Some even offer better trigger assemblies. But you have to weigh the cost of the original rifle and the cost of an upgrade.
Keep it clean and get a stronger spring.
For changing struts? Compresses spring to make shorter for removal and safety Hold spring so it doesn't expand and cause personal or property damage
It would hurt it. Changing the spring will make the pedal harder to push down. The spring pulls the pedal up.
It depends on the model. Some manufactures will sell you one or replace it if it is under warranty. Or check the web for "air gun repair", there are shops that make a living repairing airguns.
Yes it does and it will eventually destroy the seals. Never use and oil on an airgun always use Crosman Pellgun or RWS oil they are designed for airgun seals.
You can start by looking up "air gun Repair" on the web and have an airgun shop "TUNE" it for you or you can add some Crosman Pellgun oil to your pellets. (Don't soak them) just a few drops and this will lubricate the pellets and the barrel.
Yes.Becuase Changing Parts Does Make It A Little Stronger Or a little Weaker So It Depends How You Custumize it But Yes It Does Do Good To The Bey.
Unless you have the knowledge and the tools to fix it, I don't suggest you try to make repairs yourself. I would do a search on the web for "airgun repair" and select a repair shop that can make the necessary repairs. There are shops that make a living repairing airgns.

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.
