Hello 6.8 gurus! I'm coming over from ARFcom as I'm sure alot of you have in search of more answers regarding the 6.8. I have been in limbo between the 6.8 and 6.5 but the more research I have put into the 6.8 it seems the way to go. Though, I did just read last night that the 6.8 is really designed for barrel lengths between 14.5 and 16 which poses a problem as I want my 6.8 to be a 18" SPR. I want the SPC II chamber in I believe 1/10 twist. I'm sure the 2 inches doesn't make a difference in over all performance (no puns intended) but that's what I want to build for my next project. Let me know what you all think!
