Can any of you enlighten me as to the difference between a cut riffled barrel and a button barrel? Pros, cons? The assumption that others have made based on the pictures of the machinery is that it will be a button barrel. Which is what I believe LW was also producing. By comparison what does JP, GAP, KAC, POF, LMT use?

LaRue now making their own barrels

The LW barrels that Larue uses are polygonal rifling. I'm not sure how those are made, or if Larue is sticking with that rifling type our going to button, cut or hammer forged.
The method rifling a barrel, is not as important as the quality of the finished product. Cut tubes have long been a favorite of many High Power shooters as there is/was a belief that they shot better throughout their life, button rifled barrels are just as accurate, and in the last decade have set numerous records around the world, Lilja for example. Hammer forged tubes are the type of barrel used on more than half the guns produced, Rem's tubes are hammer forged. No type of rifling has a lock on "most accurate", or "best" some things like chrome lining (FN is an example) when done right does deliver MUCH longer tube life. Those that claim one type or the other is superior, are just fooling themselves and refusing to believe the scores set by "the other type". I think it boils down the care, attention and demand for quality the mfg puts into his product-in other words it not the oven, but the baker.
I got about three sentences into this and then.... OMG WTF IDK Acronyms. Seems like there ought to be an Acronym for Acronym doesn't it.
I was under the impression that while chrome lining does extend the life of a barrel, it can also be a detriment to accuracy as the chrome never actually is truly even.....as goes the argument for nitride. I am merely asking for knowledge....

Why? Ease of manufacturing or expected accuracy of that design? Or because that's what LW used and what some of his customers may expect?
Not arguing, just wondering what the rationale is.
The problem with chrome lining isn't the chrome it is the quality of the tube prior to chroming. You may recall the FN sniper rifles tubes are chrome lined, 10-15,000 capable, with very good accuracy. I don't know the exact ins and outs, but my guess is any of the high quality barrel shops could make a tube ready to be chrome lined and have the same results, as long as those doing the chrome work were as careful and dedicated to quality as they were. I'd also add, IMHO, no "treatment" or plating will make an average barrel a world record setting tube! Every few years someone comes out with a "magic bore oil treatment" just rub some down your bore and WaaLaa all your hopes and dreams will be answered! The only hopes it ever answers is the charlatan that sells the stuff. Good tubes are made by good tube makers, many have different ways of reaching the same goal but the good ones reach it consistently.
I believe many manufacturers have gone that direction because of believed better accuracy, and Mark stands by his product no matter what so going to a button or cut would wouldn't make sense since he already knows what works.
An interest free loan? How about a bunch of folks got the gun before their state passed laws prohibiting future purchases? You didn't ask me, but I'll tell you anyhow. I'm one of those guys. Without his shipping the lowers out to us, I would have SOL. Connecticut passed the law such that it was in effect the day the governor signed it. No time for any last minute purchases. Will it be a bit of a wait? Yeah, but someday beats the crap out of never.
Poison123, I'm guessing you don't live in one of the affected states.

There are certainly .5MOA rifles that are hammer forged and, less commonly for the reasons you stated, some .5MOA rifles that are chrome lined . I have never heard of a benchrest rifle with a barrel that is either. On the hammer forged side of this the reason may be that to do it well is much more expensive to do it well and therefore it seems the best barrels are from the big manufacturers who, while they may want to do .5 in some selected models, do not care about .1 or .2 benchrest numbers ever. That market does not consist of enough people to matter as to get that kind of accuracy from any barrel requires a great deal of loading and shooting knowledge as well.
What does all this mean for Larue, He is looking for .5MOA so I think he could get it using any of the above tech provided his QC is good enough.
LaRue wasn't the only one who did that. GAP, JP, and several others did the exact same thing.
More information (and disinformation, and fanboy BS and...well...you get the idea) here than you'd ever want:
It's true, we?ve had you over the proverbial barrel ... - AR15.COM
how many of you waiting feel better now - AR15.COM
Fan boi raving and Marks disgusting behaviour towards other people especially industry professionals who treat him with respect had me cancelling my orders.... I don't care if his rifle will shoot .01MAO with a blind guy behind the rifle, his attitude disgusts me, and shows contempt for every other product and person who doesn't lick his boots.
Please see this article on barrel making. It explains the mfg diffs between cut and button rifling etc. from a technical standpoint (albeit for beginners) The Rifleman's Journal: Equipment: The Making of a Rifled Barrel
Everyone has had great results with a variety of rifling methods. I think this might actually answer your question.
Most of the current cut rifled barrel makers have completely rebuilt the old WWI and II machines and upgraded them with CNC controls.
The Mil/LE program has been discontinued for since winter 2012 and their backlog only gets worse... just I would mention that. Otherwise I would gladly take advantage of it. Lol.
Funny how this thread really got derailed. It's threads like this that really take away from the quality of forums in my opinion. I've lurked on this place for years and had an old account that I would post things on from time to time. It seems like there is more and more of this fan boy shit going on that spins out of control. This board used to be much better than that...

The sad part is that I understood the whole thing....
I have a LaRue on order, so I'll weigh in with the fact that I don't care if the barrel is made of frozen squirrel poop. If the product lives up to the reputation, then I'll be happy with it. I'm not a good enought shooter to recognize the difference in a .7 MOA gun and a .5 MOA gun. I just want to shoot stuff from far away.
All that being said, I've been waiting for almost a year, and that seems excessive to me.
I agree the wait out of control. I've got a 762 predatAR on order right now but I've been eyeballing a GAP 10 lately. I have a 556 predatAR and its a .5 gun. I've also got several larue mounts. Every product I've seen from them has been top notch. That being said, the lack of communication to those who have predatOBRs on order is appalling. I'm sure any barrel produced by larue will be great but why not just produce rifles with the same ones they've been using until they can make the switch?
So I received my OBR 7.62 in March after a 34 week wait. With the weather we had this spring(it was winter until May), I have only put about 150rds through it. It shoots INCREDIBLE even with this amateur behind the gun. The interesting part is, other than running a patch through it before I shot it, I hadn't cleaned it yet, until today. I get finished up with the cleaning, and look down the tube with the light to check out over, and mine does not have polygonal rifling. I must have one of these newer barrels? I hate wasting ammo on paper targets, but I may have to do elfsters 100yd shootout just for review purposes?
I placed my order (OBR) at the 2011 LARue shoot. I cancelled it in March of this year after 3 delays. While the SCAR I bought in October of last year certainly is not a LaRue, at least I have it. Another guy that was there with me still does not have his.......2 years later!
I cancelled mine going on a 10 month wait. Only because I found a vendor that had one in stock and sold it to me. Maybe $100 over msrp. They can be had.
