| I am building my first AR-15 and I am trying to decide on a barrel. I want a 20" heavy barrel and I am having some trouble finding a barrel (mainly due to barrels being in stock). Although, I have some confusion over barrel types. There is a 223, 223 Wylde and 5.56 NATO. So, please, someone tell me the difference. Also, barrel recommendations are accepted. |

In order of most accurate to least: Wylde>223>556
In order of most compatible to least: 556>Wylde>223 Basically, .223 is the original Remington commercial spec chambering, 5.56 is the Mil. spec chambering, and .223 Wylde is a "get both" chambering that attempts to allow for higher Mil. spec pressures while keeping the .223 accuracy. Most varmit/bull barrels will be chambered in .223 Wylde and most regular AR barrels will have 5.56 chambers; the .223 chambering has sort of fallen out of favor, so you won't find it widely available. As for a heavy profile 20", that has also fallen out of favor, so you will be hard pressed to find them available as well. You might want to try JSE Surplus. |
