Really an 18 barrel is fully capable of shooting to 800+ yards, especially at higher elevations. If your wanting to buy a complete upper or rifle I suggest you look at the LaRue Ultimate upper in 6.5 Grendel, Wilson Combat, Alexander Arms, Aero Precision/Ballistic Advantage, Odin Works or Faxon.
I have a Cz 527 bolt action in 6.5 Grendel and it has a 24 barrel but I wish it was a little shorter. As a 24 barrel the Cz handles ok but an AR-15 with 24 barrel are basically very difficult to shoot off hand. I have a 20 AR-15 in 6.5 Grendel with plain muzzle and I wouldnt hesitate using it for hunting.
In my opinion 24 barrel AR-15s are best shot from prone, bench or shooting stand. For hog hunting Id prefer a barrel that was shorter and quicker handling. What barrel length did you use hog hunting, Im betting it was a barrel shorter than 24 in 5.56/223.
