Expensive, but nice. Won't work for me, though, as I'm SBRing a Scorpion Carbine. Decided to go with an HBI free-float handguard so I can remove it and attache my 3-Lug to the end of the barrel. Don't need the barrel nut any more, either. I'd say my new handguard, plus a CZ pistol length barrel threaded in 1/2 x 28 will come in near the price of that fluted barrel, plus I never need to worry about a barrel nut again
