    (2) Do you know the cleaning patterns of the operators? Are these guys who never clean their barrels and just occasionally lube the BCG with some CLP or lube? Any idea if the unreliability is evident with a recently cleaned weapon or only after many hundred rounds? I'm wondering if the .224-throated Wylde throat can't tolerate as many rounds between cleanings as a more generous .2265-.2270-throated NATO chamber? But run brush through the throat every so often, and the problem disappears? Just a theory......

    No worries, I know you don't mean it that way.

    (1) I am not sure they were true Wylde chambers, that is what the supplier had told me, I think there may be several different knock offs of the Wylde chamber different manufactures are using.

    (2) I was the one using the barrels ( I had several different barrels from different manufactures) , they were all new, I cleaned them very well before using them. They all had problems with tight chambers, more so with the cheep wolf ammo than the higher priced ammo, but did have some problems with even true mil.spec. ammo. I can't say if they were true Wylde chambered barrels or not, but I came to the conclusion that a rifle needs to work before you worry about it being accurate.
    I have laid to rest my curiosity about the Wylde and other non Nato chambers and have stuck to true Nato 5.56 barrels. I know we should clean our barrels, I have been putting allot of rounds through a couple of my gas piston TE uppers ( 5.56 Nato chambers ) and even after 7000-8000 rounds with out cleaning they are still working. So I would say yes the Nato chamber is the way to go in a combat rifle........................AD

    Thanx.

    Besides Rock River, who else chambers barrels using a Wylde chamber? Any large mfg's, or are you talking smaller, boutique shops (e.g., Noveske, White Oak, Compass Lake, etc.)?

    As I recall one of them was a RR barrel, the other I am not sure who actually machined it as I got it from one of my buddies who sells AR parts, but I was told it was a Wylde chamber.
    The barrel was given to me, so I used it on my first attempt at building my piston upper idea, figured if my attempt didn't work I wouldn't be out of any $$........

    I dont think any of the major companys use anything other than Nato, unless its a dedicated target barrel.

    I checked Rock River's website, and according to it, all current-production carbine barrels are 5.56 NATO, and Wylde's are chambered only in 20" or 24" varmint barrels.

    All I can say is that the Wylde chamber doesn't work with hot Hirtenberger surplus ammo.

    Is there some dimension you're aware of that makes the Wylde less reliable? Is it the throat dimension that you believe detracts from it's relaibility? Have you seen Randall's posted reamer dimensions? Have you seen the data Ned posted in the SWAT article?
    Yes, a TRUE wylde chamber SHOULD be ok, but to my knowledge we have never actually seen ANY manufacturer make one. They generally make them much closer to a .223 chamber.

    I have read Ned's article (very good). I also own one of Ned's 556 reamers and it does not lie. The majority of companies (like RRA) stamp 556 NATO on their barrels, but they are not. They tend to use a "version" of the 223 wylde chamber and is the reason why I get back so much material when doing reaming.

    Are reamers produced to the true dimensions?

    Yes (if you order them that way).

    OK, in the above context, who are "they"? There have been many references throughout this thread that many manufacturers produce Wylde chambered weapons, yet the only one I'm aware of is Rock River, and that's for their 20" and 24" barrels. Whether true versions, or tighter variants, who else besides RRA claims to produce Wylde-chambered weapons?
