I assume you want an original AK-47, like the REAL one that first came out around 1947-49 or so.
Well, that gun actually is VERY different from your SAR-1. For starters, your SAR-1 has a "stamped" receiver, meaning it was made from steel stampings, whereas the AK-47 has a milled receiver, drilled out from a solid block of steel. As a result, the SAR-1 is known as an AKM vs. an AK-47. It's much lighter as well. Your gun is around 7 lbs vs. the AK-47's 9 lbs due to its milled receiver.
As for the bolt carrier, it is not stainless steel, but rather it is chrome lined for corrosion resistance and better lubricity. I'm not sure who sells chrome lined bolts and bolt carriers, but I'm sure Campy, Templar, RotDorn or somebody knows that answer.
What compensator are you refering to? The original AK-47 did not have a compensator on it. The "slant brake" compensator was introduced on the AKM I believe, while the -74 style came about on the 5.45 AK-74. As for legality, as long as it's permanently pinned or welded on, you're good to go.
If you want a rifle as close as possible to the original AK-47, check out Arsenal (of Las Vegas). They have a new "classic" rifle with a wood stock and milled receiver. If you want a slant brake on your SAR-1, just find a good gunsmith to clean the gun up for you. You could make your SAR-1 look like an awesome AKM.
I wish I was at my dorm computer, because I would have been able to give you some links.
