Sometime ago during a dry-firing session with my Anschütz, a "thing" fell from the inside of the mechanism (see picture). Judging from its appearance it's part of a spring. I've looked at the parts diagram for the 2002 several times over without being able to trace it. The nearest I came to it is a spring that I saw in a picture of a trigger assembly for a Anbschütz .22 rifle, this would be the spring which sits around the firing pin, except that I don't know if this same spring is used for the 2002. So far my rifle has continued to perform as usual but I would like to get it fixed before disaster (TOUCH WOOD!!!) strikes. Could someone please identify the part for me?
