MEC 304G Rubber Grommet
Fits under the powder & shot bottles, 1 per package
This part is absolutely essential for a tight seal around the charge bar. Keep an extra one around, because you'll need it eventually.
If your powder drops are inconsistent, then you could be creating dangerous loads. That's why you need to routinely check your powder drops with a reliable scale. Also, you need to check this part to make sure it isn't worn. Replace it immediately if it looks the least bit worn.
