MICROMOA TRACK™ 14.5" FLUTED BARREL, MIDLENGTH -- 5.56
The specs on these barrels read like a dream sheet
The patented hybrid polygonal rifling allows these barrels to use smaller than normal gas ports thanks to superior gas seals, and this method of rifling has been used to set accuracy world records. Combined with the use of tough, durable steel, and tough, nitride hardening, these barrels are a blend of being both accurate and tough as hell. The barrel extensions are nitrided along with the barrels, and retorqued after nitriding before being pinned in place. Sub MOA accuracy with match grade ammo, or your money back! |

You really should make some 308 barrels.

Nice barrel; however, this is not a patented product. The number you provided is the publication number and inventor has been sent a final rejection notice.

Is that an actual photo of the 14.5 or is it the 13.7 or 12.5? The 14.5's seem to have more barrel beyond the midlength gas system. Is this a different length gas system?

Going back on track, what benefits are there from having a smaller gas port? Thank you, fixed! The tighter gas seal results in increased gas port pressure, so a smaller gas port is required to compensate for that. Quoted:

WeaponOutfitters -
In your add you state it has a 5.56 NATO chamber. When I look at it on your site it says "MMOA-14.5-WyldeMidFluted". What is the chamber? |

Anyone else have something that look like crystals around the barrel extension and pin? Could it be salt creep? I googled around for pics but couldn't find any related to barrels specifically. I'm away from my camera that has the pics, but I'll post them tonight or in the A.M.
-Thanks |

Quoted: The specs on these barrels read like a dream sheet The barrel extensions are nitrided along with the barrels, and retorqued after nitriding before being pinned in place. Sub MOA accuracy with match grade ammo, or your money back! The other side of the coin is the idea of sub-moa accuracy out of a 14.5" barrel in 223W (or 556N or whatever). It seems such accuracy claims would be more appropriate for a 308W and 6.5CM. Don't mean to be a troll, honestly. Having said that, if I understood the inherent advantage of this half-poly, half-enfield rifling...I would love to see it in a 24" 6.5CM barrel....esp with the nitride processing (though I'd prefer Melonite QPQ) PS. I think the better practice is to nitride without the bbl extension on. Or to nitride the bbl and the bbl extension separately, then to pin extension on. ...or am I mistaken? I think there was some heavy discussion on this at various places, and there were large complaints of salt drip. But I could be mistaken. But I can say for sure that there is no real advantage to nitrid'ing the extension....the extension is not exposed to hot gas erosion and rust is simply a non-issue on an extension. |

What part of sub-MOA 5.56/.223 is unfamiliar to you, and how does accuracy differ significantly from .308 or 6.5CM?
Extensions aren't pinned on. Nice sounding barrels. Any word yet on if 13.7" and the BE Meyers Saker will pin up to 16"? |

Ok, ordered a new charger, not sure when it'll be here, so for now iPotato pics will have to do till I can get the better ones off my camera.
Regarding this substance, it's "growing", don't even know if it was visible when it first got here, and I looked it over well, now it's even more pronounced than when I took the original pics. And it's hard to tell in these pics, but it's definitely crystalline in nature, they reflect light like crazy. 
What's the verdict guys? Is it leftover salt residue? If so, what's the next step? Thanks |

If so, what's the next step? Thanks The technical name for meloniting is "salt bath carbonitriding." What you've got there is remnants of the salts associated with the process. Normally they are rinsed off in water but the rinse water was probably a bit oversaturated. Simply rinse it with warm water then wipe it dry and you'll be fine. Might want to keep it off your clothes though because it's usually a caustic salt that is used. |

Might want to keep it off your clothes though because it's usually a caustic salt that is used. Yeah, I'm pretty familiar with the process, I was 99% sure it was salt bath residue, just wanted a definitive answer as to the best way to "neutralize" the salts to prevent future problems. Thanks for the answer though, and reminder I needed to update the thread. Should have came back and posted, I talked with Roy, as well as some other folks in the industry before I remembered that Roy's preferred contact method is email. Answer was remove the leftover salts physically first, then saturate with or soak in oil, which I did. Well, actually, I removed them, cleaned best I could, then stuck the barrel extension down in a pot of boiling water for 20 minutes. I'm not sure not sure when they'll get any more in, didn't want any problems, it's a keeper that's going on one of my billet receiver sets.
It's been about a week, and there absolutely no residue showing. Now if I can just get some time to assemble everything in the next couple of weeks and get some rounds down range I'll be a happy camper.

Please don't join the masses that call CMV "4150 CMV". 4150 ordinance steel has zero tolerance for vanadium. Once you add vanadium it is no longer 4150, it's just CMV.

I would still like some verification on the chamber.
I saw this thread when they were in stock and I passed because all I could think of was too bad they did not use a Wylde chamber. When they were out of stock I noticed the word Wylde in the part number. |

If you weren't such a smart ass I wouldn't embarrass you, so here ya go. It's actually MIL-B-11595E I have done plenty of reading and it wasn't from a brand's website. There are hundreds of pages of actual MILSPEC if you search. MIL-B-11595E simply refers to less than 2" bar alloys (notice the plural form of alloy) of which there are three types: 4150, resulfurized, and chrome-moly-vanadium. Refer to page 3. If you need anymore direction just ask and happy reading. |

The fact that it is either 4150 or CMV is from a metallurgic standpoint. CMV is without question a part of the 4150 ORD family as shown in table I on page 3. I'm not claiming any manufacturers ignorance. It's my opinion that manufacturers add 4150 to their description to give under educated customers a warm, fuzzy with the abundance of 4140 barrels on the civilian market. It's just a technicality that bugs me. |
