In the event that your snap ring is destroyed or lost, this is the proper replacement. This is a new, unused snap ring. These are near-impossible to remove without the proper tool. I recommend the Proto J390 Ring Pliers for removing this part. They are cheap, effective, and fantastic quality.
This is part number 14 in the blow-up diagram.
Regardless of recommendations on this page, I am not liable for damage to your marker or regulator.
