5.56 Match vs .223 Wylde Chamber

[cory]

Not a Grendel question, but there's so much more knowledge here with only a marginal amount of noise as compared to other forums. So I brought my question here hoping y'all could enlighten me.

What makes the 5.56 match chamber different from a 5.56 chamber?

Is there any advantage to either of these chambers over the other in a magazine fed AR15?

Thanks.

There are multiple 5.56 "Match" chambers, .223 "Match" chambers and other variants. Most match chambers simply have a tighter neck, and some change the leade.

Common consensus is that the Wylde chamber is the best compromise for an AR shooter wanting the best of both worlds when it comes the reliability and accuracy in an AR shooting 5.56 and .223.

Alright, so has anyone ran a 12.5" mid length .223 wylde? If so, what was your gas port size?
