i currently have 7 - 6.8's, 2 - 5.56/s, 2 - 308's, 1 - 7/63X39. all of the Ar15 frame but one run ARP barrels,bolts, muzzle devices. i could not be happier with them.
I have had 2 each of ARP 16", 18" and 20" barrels. The 16" were accurate but the 18"ers we easier to find the optimum load so sold the 16". I got a 20" just to see if there was as much improvement compared to going from 16 to 18". There was in a few ways but the 20" didn't have the balance of the 18" (which felt the same as the 16"). I did like the added performance of the 20" for hunting so had the barrel fluted so I now have an 18" and 20". My hunting buddy talked me out of the 2nd 18" and won't give it back and my son has the 20" for hunting.The ARP barrel/bolts REALLY sucked me in today when I saw the incredible price and features of their barrels. Feedback on accuracy of the 16-18" setups?
