Description
Some people love classic things. Some of those classic-loving people love classic firearms. You know the type. They can list every good thing about the 1911 in alphabetical order, or tell ya all about how the M-16 used to “jam like a sumbitch.” They might even have personal experience on the matter.
If you’re the type, you’ll love this build kit, because it’ll get you most of the parts you need to build an AR with an old-school M4A2 look. Everything about this kit screams “mil-spec,” too, except for the barrel treatment: We ditched chrome lining in favor of a full phosphate treatment to provide even more accuracy and better protection against the elements.
