Hey guys. I really wanted to install some shs 12:1 or 13:1 gears in my nemesis x9 but I heard that people who did this before had a hard time getting them to work after. The problme i am refering to can be seen here: https://www.reddit.com/r/airsoft/comments/bkgxp2/ca_nemesis_gear_upgrade/emhenls/ (read the whole thread it is not very long). I was just wondering if there is a way to get around this problem before I buy a new gear set. Thanks.
