I'm selling my F2000 that i bought back around 2010, when it first came out on the market , didn't use it since a long time and was just maintained in a safe place
Never opened the Gearbox , the only problem is that the tiny lever (selector plate) that connects the trigger contact ( every f2000 had that problem back then ...) is not reaching properly , but a lot of forum are explaining how to resolve this problem
Some esthetic parts are missing :
The reloading lever
The rubber stock pad , which didn't suffer from misuses but the time had it's toll on it
I guess you can order those parts on the G&G website
Just ask if you have more question and of course i can send more detailed pics !
