For a firearm to be Mil-Spec, every aspect has to meet criteria defined by the military to often include dimensions, materials, testing of parts, etc. A Mil-Spec part and/or small arm system is ultimately approved by a U.S. government inspector.
A Mil-Spec firearm and its components must be evaluated and certified by the government for it to be Mil-Spec. In the case of false advertising, I loathe gun manufacturers who apply the term to parts or firearms that mislead consumers for marketing purposes. It's easy to see that companies are not offering civilian-legal Mil-Spec ARs because the military's feature Mil-Spec select-fire automatic or burst trigger systems.
I see and hear a lot of gun experts label a company's basic trigger as Mil-Spec. Even some of my colleagues do it. What they are describing is a semiautomatic-only trigger assembly that is not in the military's system. There are several different makes and designs of these basic triggers, so it is unfair to generally describe a heavy or gritty trigger as simply being Mil-Spec. There's more to a Mil-Spec trigger assembly than a single disconnector.
To this day, I love working on ARs and creating clones of all types of modern-day small arms. Though I tend to go deep in the minutia of finding correct government-issued bolt carrier groups and accessories, all I ever end up with is a copy that's not Mil-Spec. The closest civilian-legal clones to a current-issue Mil-Spec AR are the Colt LE6920 starting at $999 (colt.com) and the new FN 15 Military Collector M4 and M16 models for $1,749 (fnamerica.com).
