DO YOU NEED A FILE?
If your safety selector lever looks like the selector below, you will have to file down and polish the selector so it has a nice, smooth ramp to it. The perfect file for this can be found from Amazon for $8, or you can purchase it from us for $5 ( we will also include high-grit sandpaper for polishing. If you are afraid of ruining your selector lever, don’t worry, you can purchase a replacement form directly from Fostech’s website. Full instructions for how to file the safety selector can be found HERE.
