Hello, I recently purchased a New Colt LEO 6920 and tonight I dissembled it to inspect, clean and lubricate it properly. I was very careful when I removed the extractor, I have another AR and I know that the spring can sometimes fall off. When I removed the extractor I was really surprised to see that there was no black O-ring under the spring, it definitely was not there before I took the bolt apart. My question is do all Colt 6920s bolt extractors come standard with an O-ring, or is it normal for them to look like the one in my photograph? If so I guess the dealer who sold the gun would gladly supply a new O-ring or I would be willing to purchase one from a CGN member.
