Some people love classic things. Some of those classic-loving people love classic firearms. Maybe that's you: You can list every good thing about the 1911 in alphabetical order, or tell a friend about how the M-16 used to "jam like a sumbitch." You might even have personal experience, there.

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 phosphte treatment to provide even more accuracy and better protection against the elements.

What’s Included

This kit is not a firearm. It includes an assembled upper receiver, bolt carrier group, lower parts kit, and buffer assembly with buttstock.
