May I suggest the Savage 10 FCP-K in .223?
Your criteria was: Black, portable, accurate
This is black as it is finished with a matte black finish.
This is portable at 9.9 lbs (typical for a heavy barrel rifle)
This is accurate, or at least it should be, what with a heavy fluted barrel with a #####in muzzle brake.
With a 1-in-9 twist you should be able to shoot up to 75-77 gr bullets no problem. The detachable box mag is always handy as well.
I have seen these around. Last I checked Elwood Epps had one, same as Italian Sporting Goods, though that was several months ago. Price should be south of $1000. If you dump another $1000 into good glass and mounts, you should be doing pretty good. Of course, you will want to hand-load ammo for the best accuracy, but that is a whole other can of worms.
If Savage doesn't work for you, there are similar rigs sold by other companies, such as Remington. A model 700 with 5R rifiling would be nice.
