Thanks for the help but I already tried Hoppes N0.9 with no results. Could it be the phos finish on the parts is not very durable.

I was reading abouty these "O" rings. How long do they last. I just bought this gun and expect it to last many years without service. My M14 is 20 years old and I have had to do nothing to it.

Hi I am new to this group. I just purchased a MR1, the gun looks great and shoots fast but I have one big complaint. I noticed that the ejected shells about 50% of the time are ejected back not to the side. I have noticed some damage on my receiver from the casings hitting it. At first I noticed 3 and thought that I did not notice them when I purchased the gun but after shooting 2 boxes of shells the number of marks have increased. These marks do not come off and I fear they are permanent. I am afraid to think what the gun will look like after 20 boxes of shells. I have noticed these marks on a youtube video. Are you guys haveing this same issue. Also with the shells going back the guys at the local gun range are not going to like me.
