If you are mechanically inclined you can find a description of how to change the spring online and save yourself the gun smithing cost of the springs installation. However if you are not so good with such things its worth your money to invest in having someone skilled do it for you.

Anyway would this spring work for a kraken? If yes then I'll point my friend in the direction he needs to go...
