For a while now there has been a lot of talk about how ineffective the 5.56 service round is. It’s all over the internet gun boards and the popular slick newsstand gun magazines. Time and time again we are all told how the 5.56 is a 200-yard gun, or if you’re using a carbine, you’re stuck with a 50-yard gun. Everyone knows this, it’s just plain common sense! The problem is, it’s not really true. A whole lot of people sound off about something they really don’t know much about and have zero experience with. This amused me for a few years, then as more and more time passed it really started to bug me to the point of aggravation. A certain type will always repeat the same inaccurate info and we all know that. The problem is that it causes those in military service to lose confidence in their service weapon and what it can do. Confidence in your tools is an important thing, if you believe in and know for a fact what your rifle can do, you shoot it better.
Most serious followers of the AR15 platform know about the MK12 rifles and have read stories about 500 to 800-yard kills and how effective it has been in the GWOT. A few are at least vaguely familiar with High Power service rifle matches. But they assume any AR15 type rifle that can be used for these ranges is by necessity some super customized and specialized weapon. Obviously there is truth in that. To shoot a winning score at Camp Perry you have to have some specialized rifle work done and use special ammo. When these accomplishments are brought up in discussion, they are shot down by the people who “know better” because they are not the same guns issued out to troops or normal civilian users for self protection. And so it goes on and on, that the AR15 is a 200-yard gun.
It is not. It will do more than most believe, and it will do it with military-issue ammo.
