Mini 14 Bolt Peen
While cleaning and lubing I noted some peening on the bolt where it strikes the hammer. You can (hopefully) see where some material has rolled over a bit. Should I just stone it back a bit and perhaps polish the area, or is this cause to send it into Ruger. It's a 582 series I bought in 2013...
