.223 Wylde barrels??

[AirMech74]

What is the difference and are there any pros and cons? I just obtained an AR pistol and noticed that the barrel is a 7.5" SS .223 Wylde....I'm not familiar with those.

You can shoot 5.56 NATO out of a 223 Wylde.

Yep, it will allow you to shoot 5.56 without pressure issues, but offers better accuracy potential accuracy with .223 than the 5.56 chamber. I see no practical benefit over a standard 5.56 chamber in a 7.5" pistol barrel.

Will twist rate matter?

Depends on what weight bullet you intend to run. If less than 69gr, 1 in 9 is OK. Definitely 1 in 7 if anything heavier.

Sounds like the barrel length won't matter on twist rate. Makes sense.

It's a tighter chamber than 5.56, so tends to provide better accuracy and brass life, but may not be as reliable when dirty. I like a 5.56 chamber on anything that may be used for a fighting role.

I took a closer look at mine, its a 1 in 7, I'm just not sure of the manufacturer.
