I plan to use my new ultrasonic cleaner (Christmas present) to clean a Geissele coated BCG.
I plan to detail-strip the bolt to remove the rubber extractor o-ring.
I also plan to put the pieces in a ziplock back with a mix of Hornady ultrasonic gun cleaner (properly diluted), to avoid having to have the tank contaminated with the residue and for simplicity in keeping track of the parts.
Should I immerse the ziplock in water in the ultrasonic tank, as well?
Any other tips, or thoughts?
