Some people have a weakness for classic things. Some of those classic-loving people reminisce about classic firearms. You probably know someone like this. They can list everything that makes the 1911 timeless in alphabetical order, or tell ya all about how the M-16 used to "jam like a sumbitch." They might even have personal experience with the damned thing. If you're the type, you'll love this build kit, because you'll get most of the parts you need to build an AR with an old-school M4A2 look. Everything about this kit is all about “mil-spec,” too, except for the barrel treatment: We axed the chrome lining in the barrel in favor of a full phosphate treatment to provide even more accuracy and better protection against the elements.
