Cryogenically Treated Barrel??

[pipman]

So I'm itching to build another AR, but this time I want something I can do some distance shooting with. Not too far, maybe 500-600 yards with a .223. Anyway, at first I was thinking of building an upper, but then I was on Rock River Arms site and seen they have some uppers that are basically what I am looking for. One that really caught my eye was the Predator Pursuid Rifle Length. While I was looking at it I noticed that it is cryogenically treated. I was just wondering if anyone has a cryogenically treated barrel, either purchashed that way or sent off to get treated. What are your experiences, good and bad? Is it worth it? I've seen statements that it increased accuracy, but I also found a statement made by Armalite stating that it is not worth it.

I am a believer of Cryogenically treated barrels. But in my IMHO it can't make an average barrel great. If accuracy was my goal i would buy a barrel from a manufacturer that is known for accuracy like Lilja Lilja Precision Rifle Barrels - 50 Caliber Precision Barrels or Krieger DCM & AR-15 just to name a couple. And if funds were still available i would still freeze it.

My barrel is Cryo treated on my AR which is a Rock River Upper. It was sent off after I bought it though. I don't have anything to compare it to. At 300 yards I ONCE achieved a 1" group of 3 shots. This was using an optic with PERFECT conditions and a rest. I have never shot this again, so did it help? I'm not sure, but I do know I am very consistant with it at 100yrds.
