I'm thinking of getting a 6.8 complete upper for my Colt AR. Shooting hogs with my Savage 308's is cool, but I really need the semi auto to kill more pigs.
I don't have much experience with this round, other than having shot one a few times...and I LIKED IT !!!
So while researching new uppers for the AR, I see 6.8 SPC and 6.8 SPC II. Anyone know the difference???
