Can someone explain the difference between the two Sendero models? When did Rem. switch production, what features are different, which are preferable, etc. I'm looking at one that I'm guessing is a sendero, although it doesn't actually say it anywhere on the gun. Stainless, fluted, ambi. palm swells, two front swivel studs, in .300 RUM. It looks a lot different than the black sendero 7 mag that I have. After I posted this, a bunch of similar threads popped up underneath and answered most of the questions I had. Sorry about that. Any other info is appreciated though. Thanks.
