As said before don't store in storage pouch, towels etc. Here on the east coast of Florida I use silicone treated rifle socks, clean and lube yearly and no rust on any of my firearms ever. I have used CLP and Eezox, both are good at rust prevention and the rifle socks help keep my rifles from being ...

The back side of the extractor should be almost flus with outside ring of bolt head. If that doesn't work a...
