There are a lot of marketing terms for the SKS; super grade, unissued, unrefurbished, matching numbers, etc. If you read enough threads on the SKS, some people don't care about these terms and just want the cheapest SKS they can find. Then again, some people say their SKS can't hit a barn and some say they shoot just fine .... I'm no SKS expert, but if you see them in a store, you can see that some come well used and the bolt and stripper clip guide have lots of wear and the dust cover could be well worn; it's not hard to imagine these wouldn't shoot as well as some of the SKS that look like they have never been fired. The black bayonet means it is a refurbished gun and that is considered less desirable, but nice looking SKS are harder to find these days. super grade will probably mean that there is less wear and tear on the gun and the overall shape will likely be good, but there are lots of threads about super grade SKS not meeting the expectations of people posting on cgn. SFRC is a good dealer, so not sure what you'll get ..... Post pics later if you can.
