Depends on your mechanical aptitude.

There are youtube videos out there but unless you can follow the instructions to the t I would recommend against it. I wouldn't pay more than $30+tax for a spring swap tbh, it's like 25 minutes worth of work tops for a competent guntech.

If you do decide to do a spring swap on your own, make sure you don't touch anything else in the gun and make sure the piston is correctly on the gearbox "rails" afterwards. Also good idea to have a small precision screwdriver to hold the spring guide in place or the spring will pop out and your gearbox will not only be in pieces but you might even loose some small parts.
