I'm currently without a Steel Force again for the 6th time returning these poorly designed and flawed guns. After calling Umarex again and again, I finally spoke with someone who said it's the gear wheel that breaks and Umarex USA is are nothing more shipping center share with Walther firearms,that send out new guns that are under currently under warrenty. Also they don't carry spare parts and confessed the employees are not gun tech's. She claimed there are very few Steel Forces out there that have "not broke yet" as she was claiming only a matter of time before they do. Umarex Germany is aware of the problem and does nothing as of yet to fix this gear wheel flaw. BUYER BEWARE the chances your gun will prolly break but when u call them ask for Umarex to pay for your shipping ( as they did for me several time ) and be ready to have it break over and over again with no idea if they will ever fix this designer ongoing flaw of 3 years!
