I don't get the "black rifle" thing . . .
I've owned two of them, and a Rem. 700 PSS "sniper" in .223 Ackley Imp. Sorry, I just don't care for the caliber, which is why they're all sold.
That said . . . I'm a big fan of Bushmaster. Seems like they had the govt. contract for the Dept. of Defense. You can get the stock config you want, heavy barrel, floated fore-end. Flat top sight rail and all the rest, off the rack from Bushmaster. Then you add a custom two stage trigger, and you're set to go.
I much prefer the AK-47, but then I'm not doing any "fine detail work" with it. What I'm getting is a small, light carbine with huge ammo capacity, and a potent ammo -- 7.62 X 39mm is more potent at the "carbine" range -- 300 yds or less. Larger diameter bullet, and twice the bullet weight of the AR-15.
These days, for the "reach out and touch" stuff . . . I'm doing a Weatherby Vanguard, 30-06, Leupold VXII, 3 - 9x 40 mm scope, duplex reticle. I found in a pawn shop for $350 out the door.
