The reverse of how you took it apart. I would look on the web to try to find drawings of how to assemble the BB gun. Try looking at the company that made the BB gun first, some offer drawings of the gun and how to assemble it. www.Crosman.com offer this for most of their guns. OR you can take it to an Airgun repair shop to heve it re-assembled. Check "Airgun repair" on the Net and find a shop close to you.
See the link below for the drawing.
The Internal Magazine is the compartment that holds the BB's ready to be fired. It usually comes out of the gun and you put the BB's into it then put it back into the gun.
Best left to a professional.

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
Which model? All the different models are assembled differently.
Contact an Air Gun repair shop near you. Look on the Web under "Airgun repair or Air Gun Repair" and send it to a location close to you. It very hard to help you if you don't state the name, model and make of the BB gun you took apart.
I would contact the manufacture and ask them for help.
Put the Safety on first. Make sure the BB gun is not charged or cocked and unloaded. If the BB is jammed in the barrel you will have to take a .177 cleaning rod and push the BB back into the loading chamber from the front of the barrel.

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
