Hi folks,
I am working on a build now, and have my eye on one of Criterion's chrome-lined barrels with a Wylde chamber. I take it as a given that the barrel will be insanely accurate and long-lived, and I am friends with a dealer who can guarantee to get me one that is 4150 instead of 4140. However, I want to hear from people who have one of these barrels how reliable they, with their Wylde chambers, are. I know the conventional wisdom is that 5.56 NATO chambers are the most reliable, but not only have I read that a well-made Wylde is at least as, if not more reliable than the NATO spec (I have discussed this topic with Bill Wylde himself), if one looks at the actual chamber dimensions (my friend at Criterion provided me with the measurements and drawings for their chambers), all measurements but the throats diameter are actually looser than the 5.56. The only real-life reliability issue of which I have ever heard with the Wylde chamber that had actually happened and is not just theory, is the issue of difficulty extracting and ejecting a live round. I gather that this problem only really occurs with cheaper barrels like the RRA, but I'm wondering whether it has happened to anyone with the Criterion barrels, Basically, I am hoping people with first hand experience with Criterion's chrome-lined barrels with Wylde chambers can share their experiences with reliability. Thanks!

No Criterion experience but I have a White Oak Armory 10.5" SS Wylde chambered barrel. No reliability issues, no issues clearing the chamber, very accurate.
I shoot that upper suppressed 99% of the time. With the crud shooting suppressed creates with back pressure you would think any feed or extraction issues would show. I do use an adjustable block, but it is set pretty open to function ok unsuppressed. I wouldn't hesitate to buy another qualility Wylde chambered barrel again. Hope this helps, JPK |
| There is no reason to doubt Bill Wylde's word on this. IMO the problem "Wylde " chambers are most likely poorly done to begin with and all reamers are not equal. I have Wylde chambers and so far they have given zero problems. A short headspaced chamber can cause extraction problems regardless of the chamber specs. |

Are we really going to do the Wylde chamber vs. the 5.56 chamber thing again?  In a match grade barrel with sub MOA quality and match grade ammo, it can enhance accuracy. In mass produced non-match barrels, it is a marketing gimmick, lipstick on a pig. It should not, however, impair reliable cycling if done properly. I have a Wylde chambered Lilja 416 stainless match barrel. I've shot a wide variety of ammo in it more out of curiosity, as it normally is fed only my match handloads. Everything, including full power 5.56, functioned fine. But then again, I've not dropped it in mud or gotten sand in the chamber. |

It is legitimate technical question. I concur with the honest observstion that the only spec that could arguably affect reliability is the tighter throat. That is to better stabilize the bullet as it makes the jump to the rifling. In a match grade barrel with sub MOA quality and match grade ammo, it can enhance accuracy.

I don't know what reliability issues you've heard but I got absolutely 0.00 problems with all of my uppers with Wylde chamber, including one with 20" Criterion chrome lined barrel. It is an moa shooter with my 55 gr blitzking match loads. Oh BTW, my RRA barreled upper has zero issues also. Of course I don't feed them with range-pick up ammo

I have a criterion hybrid chrome match barrel that's just awesome ! No issues at all http://i347.photobucket.com/albums/p460/alexfiggy1/Mobile%20Uploads/2017-03/6A1A9E95-DF7A-4031-803E-536639229D37_zpsdekg3uug.jpg |
