What is prefered chrome moly barrel or chrome lined barrel for an ar-15? Chrome-moly is the barrel steel alloy (actually chrome-moly-vanadium, 4450 by milspec). Cheaper barrels are unlined chrome-moly, while the more expensive (and, to me, desirable) barrels are hard chrome lined chrome-moly. |
| Chrome Moly will be more accurate in most cases and a chrome lined barrel will last longer and stand up to harsh environments better, I just replaced a superb CL(DD 4150 CMV HP/MP) barrel that was very accurate with a SS barrel because I wanted the most accuracy I could get. |

This. That being said, for most shooters, unless you're shooting benchrest competition or something similar, you'll never notice the very small difference in accuracy between a CL or non-CL barrel. |

True but that also depends on the chrome job, not all CL barrels are created equal. |

To add to this, if one starts with a quality barrel blank, and uses a quality chrome company, one will have a more accurate barrel than a mass produced blank with the same chrome job. I have seen quality barrel blanks with a quality chrome job shoot true MOA at 300 yards. These barrels are few and far between due to the high cost of a quality barrel blank. By quality, I mean a Douglas, Lilja, Krieger, or Lothar barrel. |

What is prefered chrome moly barrel or chrome lined barrel for an ar-15? On this site many will tell you they wouldn't touch a non-chrome lined barrel. That is their opinion and there are reasons that will support that. If you were laying in a rice paddy, soaking wet, unable to clean your rifle the chrome would clearly be a major benefit. If you had a fully automatic AR and you shot the hell out of it in combat a Mil Spec Chrome lined barrel would be what I would want. If you are Mr. Real Average Shooter either barrel will work fine. If I had two rifles in front of me and there were only a few dollars difference I would take the chrome lined one if for no other reason than resale value. If I had a shot at a good rifle for a good price and it had the chrome-moly barrel I would not hesitate to take it. I have been shooting for (I hate to admit this) fifty years. I have the first rifle I shot, a 1958 Remington, with no chrome barrel and it still looks wonderful. I have shot many a rifle, some made during the First World War (1917 time span) that have great looking bores and still shoot darn straight after almost 100 years. This is with 30-06 ammo too, not some wimpy stuff. This whole thing about barrels that are not chrome lined not lasting just doesn't hold water for anyone who is a casual shooter. Not only that, there are thousands of M-1's, M-1 carbines, M-14, etc. that have shot thousands of rounds down their non-chrome lined barrel without issue or excessive wear. I have yet to see anyone who has a verified case of a non-chrome lined barrel wearing out in less than 6,000-10,000 rounds or so. Fact is, there are many who have fired much more than that through them. I have yet to see a case of anyone with a non-chrome lined barrel that had normal and proper care that rusted or deteriorated away due to the lack of chrome lining. There are some who will tell you that if its isn't chrome lined with a 1-7 barrel then its a piece of junk and no one should own it. Its a free country, they are allowed to have their own opinions, right or wrong. I dare day there are hundreds of thousands, if not millions of good firearms out there that lack those two features and still manage to live a useful and productive life. To each their own. |
| preferred? most in the know prefer chrome lining because of resale value & longevity, but most long range shooters prefer chromoly or stainless due to consistency in manufacturing. this isn't to say that a chrome-lined barrel can't be as accurate as a chromoly or stainless one, just that they're harder to come by. |

When they fist started chroming AR bores and chambers, there was quite a lot of variation in thickness of the chrome coating. Enough, especially at the muzzle, to influence accuracy. They've had some practice in the last 40+ years, and chrome lined bores are really, REALLY consistent and accurate. They don't, to my knowledge, replace the GI barrel in a Squad Designated Marksman rifle with a commercial, non-chromed barrel because the chrome doesn't reduce the potential accuracy of the barrel measurably, while other factors including how the barrel is mounted and supported do; these issues are addressed by truing the face of the upper and free-floating the barrel. A quality barrel is a quality barrel. If it's chrome lined, it was manufactured to be chrome lined and it will be at least 99.999999999% as accurate as an otherwise identical, well made chrome moly barrel. It all depends on how much time and effort the maker puts into producing a quality barrel. |

Not everyone knows everything from birth like you. Now, can we go over the lesson plan, that you taught a while back, on why USMC S/Ss carry a sidearm? BTW, Google must not be KAC1911's friend. |
| The question is what is preffered ? The answer to that can only be one thing. It depends on who's buying the barrel and what their intended purpose is for the barrel. But to address acuracy , first he did not mention stainless in the question so it's not included in the answer. A LOT of people claim that chrome LINED is not as accurate as c-moly or unlined. This is probably do to their lack of properly breaking in the LINED barrel which in fact is nothing more than polishing the lining with bullets. In my experience, chrome lined barrels that have been properly broken in will most always shoot with or even better than an un-lined barrel. You need to avoid heat when doing this and from most of the threads I have read here and elswhere. nobody wants to take the time or use the ammo to do it right. This meens they cant expect to get the best their barrel has to give because it simply will not happen. Chrome lined barrels will last at least 3 times longer than un lined because the lining is harder than the barrel itself. If your going to pay extra for a lined barrel(HIGHLY RECOMMENDED) take the time to properly break in the lining and you will end with a accurate barrel that will be easier to clean and put a smile on your face every time you go to the range for many years......No offense intended but opinions are free so I don't expect you to beleive all this but I give you my personal guarentee if you do this you wont be dissapointed.........Jeff |
