I'm starting my first complete AR-15 build and decided to go with the 6.8 SPC round. I'm going to be using this rifle mostly for hunting and a little target shooting but can't decide on a barrel. That's where i need y'all's help, i have two barrels picked out either an 18 inch barrel with 1:11 rifling or 16 inch barrel with 1:10 rifling.
Note most of my shots will be between 50 and 150 yards and all on medium game sized game. Direct pin point accuracy is not a must. As long as i'm shooting about a golf-ball size group at 100 yards ill be happy.
