What are you looking to modify , and to what extent ?
Most BB guns are simply a smoothbore barrel , a wooden or plastic stock , and a mechanism , generally called the " action " , but more properly called a receiver , that the compressed air passes through to propel the bb down the bore toward the target.
Some type of sights are important , as well , to align the barrel with the target , so as to increase one`s ability to place your shots on the target.
Generally , sights are the first thing to be improved , followed by the trigger , to increase accuracy.
If you are looking to "modify " some BB gun to fire large numbers of BBs , with a single pull of the trigger , you are wasting your time.
Such BB machine guns were common , back before some idiots in the EPA decided Freon was bad for the ozone layer ( science doesn`t back this up , get over it ! ) , and 1lb cans of freon provided the volume of gas needed to push a cloud of BBs 20-30 yards , with poor accuracy.
You could search Ebay , better still one of the firearms oriented auction sites , and simply buy yourself a BB MG - but be prepared for sticker shock !! They are expensive , and with the passage of time , brittle , plastic . As well, one must also find a way to convert them to use a different source of compressed air.
My suggestion would be this : learn to fire one BB at a time , accurately.
Note the word " accurately " - you will enjoy it more, spend less on BBs , less on equipment , and learn something useful in the process.
After 10 years in the military , and having fired a great variety of machine guns , I have to tell you - the thrill wears off really fast !
If you know what it is you wish to improve , and how you were thinking of improving it , post a reply. I`ll keep an eye on this , and may be able to offer so tips.
But , this important ! Remember:
Be SAFE !
You could shoot your eye out !

It's a BB Gun.
A BB gun is a gun which shoots BB-size pellets, typically with the use of compressed air, or a compressed spring.
You don't magnetize the BB's. The Magnet is inside the BB gun. The gun has to be taken apart and the magnet that holds the BB's replaced. Not all designs use this method of holding BB in place.
