Mine is bad enough that it has started to wear down the black coating inside the action. I opened a tech case with Ruger and they have asked for me to send the rifle back to them to check it out. Maybe its nothing to worry about, but it seems to be causing some excessive premature wear.
I have something to say about the above comments.... http://shopwilsoncombat.com/Silicone...oductinfo/267/ Yes the inside shines up after a while. At first I was spraying down the bolt with Rem Oil and other things and the bolts still have that rough feel about it and then one day at the local gun shop the owner gave me a Wilson Combat Silicone cleaning cloth and I haven't looked back. I'll take the bolt after a few hundred rounds or every time I happen to have the bolt out and rag handy and just wipe it down/off with the rag and wipe some from the inside of the receiver AND THATS IT!. I swear this helped the feel of the bolt. It seems that the bolt doesn't react well to just having Oil on it. It says on the rag too that this stuff works for fishing reels which got me thinking. The bolt has kind of the same finish as some of the inside of reals and other stainless bare metal parts. Give this a try. Or find some Silicone Reel oil and a felt rag and make your own.
I noticed the same thing, the inside getting shiny but its the same thing with other mechanical parts that move together. I never expected the inside of the receiver to keep the same finish as new. Even Cerakoted parts show wear after a while and this finish on the RPR's is nothing to be proud of. Let it wear and smooth out then if you want get the inside and rifle Cerakoted to make it "look" better. Point is Use one of these rags and get some rounds down the barrel, it will smooth out. OH and remove that stupid O-ring off the back of the bolt if you happen to have a Gen2.
