As you decrease the length of the barrel, however, not only do you rapidly lose velocity (and hence energy), you also decrease the reliability of the weapon: the AR direct impingement gas system does not operate as smoothly when it is shortened. Now, it seems the majority of AR models on the market today are based on the 16 inch carbine barrel, a length that generally produces adequate ballistics. Any less than this length reduces the efficacy of the cartridge. The 5.56mm cartridge was originally designed to be used in a rifle with a barrel 20 inches in length. And to be honest, their arguments are not without some merit. For this project, I decided to stick with the traditional 5.56mm chambering, even though you will find many detractors who ridicule the use of this rifle cartridge in such a short barrel. pistols are nothing new, and you will find them in several different calibers.
