"You have to mike out or measure them on a mm ruler your current bushings and find out if they are 6,7,8,or 9 mm bushings.If you don't they will fall apart and eat up your gearbox.

"My gun is a MP5K. Shoots 25 RPS @ 330 FPS. These bearings worked good for about eight months. They did fit properly. But like the other review mentioned, they fell apart. No internal damage was caused. The ones I recieved were packaged in an SHS bag. Hope this helps.
