Just some info for any one interested. JP makes a one piece gas ring for DPMS/KAC style bolts called their Enhanced gas ring. As many probably know the McFarland one piece 308 Gas ring was designed for Armalite bolts but works fine for DPMS/KAC bolts... However it fits a bit loose on the bolt. I ordered one and it definitely is beefer than the McFarland and fits much nicer..... I'm just passing on some info if anyone didn't know they were available.... They are not cheap costing $10 but appear well made and fit properly compared to the McFarland.... I'm very happy with it.
