257bob Posted April 3, 2009 Report Share Posted April 3, 2009 I am going to purchase a new AR-15 upper, but I am not sure which barrel to buy. All other things being the same my two choices are 18" ss fluted 1in 8" twist or a 16" chrome lined vanadium alloy 1in 7" twist. I know the differences lenth and twist are going to make. My question is in the materials which is going to be more accurate and have more longevity. If possible what are the pros and cons to each. Any info would be greatly appreciated.

wtnhunt Posted April 3, 2009 Report Share Posted April 3, 2009 Not a smith, but think I would take the ss barrel over the chrome lined vanadium barrel granted the ss is a quality barrel. Have the wilson stainless barrel on my rock river, my dpms that I have ordered has a 24 inch stainless barrel. From what I have read the barrel being stainless or chrome lined will not make much difference in accuracy, but the stainless will likely last longer.

257bob Posted April 9, 2009 Author Report Share Posted April 9, 2009 Thanks for the input. I haven't spent much time on this forum in the last year, but wow I am shocked that there wasn't more opinion posted. The link was very helpful and I have decided to go with the stainless steel. Thank you. Quote Link to comment Share on other sites More sharing options...
