When I recieved the two rifle kits I ordered from J&T I noticed that both of them were missing the black o-ring from the ejector assembly, item 63, shown on the exploded view in the J&T Distributing AR-15 Owners Manual.Upon calling to question this, I was told that the o-ring only came on the assembled rifles sold, not on the kits and that I really did not need the part. 500 rounds later, they were right, my rifles shoot fine.
What I really want to know is what purpose the o-ring serves and what would be the expected result of installing one? grayghostusa |

It's to aid in extraction. To some it's the best thing since sliced bread, to others, it a solution in search of a problem. Here's an example. http://www.ar15.com/forums/topic.html?b=3&f=118&t=397989 |
