Most accurate semi, bolts are supremely more accurate then semi's.
I am guessing this is your first firearm? If I were you I would start with a bolt action, you can get a nice marlin bolt for just over 200 bucks. Once the novelty of blasting away in semi wears off you will want to get into accuracy.
If you want to spend just a little more for a lot more quality get a CZ 452,
a bit over 400 but it's a real beauty and shoots like a dream stock. (you may need a trigger kit, just a lighter spring so the trigger is easier to pull and breaks nice and clean)
If you heart is set on a black semi they do indeed look pretty cool, and i am looking into one myself, but just maybe not the best idea for your first.
