Leave it to a trained professional
Not economically feasible.
You need to state the model and what is wrong with it.
Send it back to the manufacture or contact the manufacture to find out who repairs your BB gun.
As far as I know Gamo never made a bb gun named the FIX. They did make a model named the CFX, but it is a rifle and shoots pellets, it's not a bb gun. I suggest you contact Gamo at the link below and ask them.
Take the bb gun apart, memorize or take a pic of the inside, find the jam ,and put it back togethor
Cheaper to buy a new one.
If its a BB Gun, Then Yes.
yes you can, but there are several complications: a. you have to load all the bb's into the clip or ammo depot, which takes a while to do because you have to hold it open to put the bb's in b. sometimes bb's will get stuck somewhere in the gun and jam it, but after a little shaking the bb's could be back where they belong or somewhere in the framework of the gun. this is really annoying to fix. when firing multiple bb's come out so it is a shotgun it is best to use airsoft(plastic) bb's, not metal bb's
I suggest the you contact an air gun repair shop to have it fixed. Try looking up "Air gun repair" on the web and have them repair it for you.
