The gun in the pics is a Crosman, but it's a clone of the Gamos. Only thing different is the end cap. The plastic cap just pulls off. Don't worry about removing the barrel, it's usually not necessary. If you use brake cleaner to degrease it might wise to wrap the barrel with aluminum foil like I did. I also plugged the transfer port with a Q-tip. Brake cleaner is not friendly to some plastics. Better safe than sorry.
