I got this at the annual NRA meeting this spring. I found this again this morning. I was going to ask this group to ID at that time, but I totally forgot. The gentleman was handing them out to everyone but didn't say what it was. I didn't ask, my quick glance made me think it was the rings used in an AR bolt. I just looked up to see what booth I was in and promptly forgot about it. It appears to me that it is a snap ring and a small plug. The plug is plastic or rubber since it has a soft feel.
Can anyone ID? Is it something I may have a use for or do i file it away?
Thanks in advance,
