.223 Remington and 5.56x45mm NATO Upper AR Rifle Assemblies

Complete AR upper barrel assemblies chambered for .223 Remington and 5.56x45mm rifles.

With your lower AR assembly and a new "pin & shoot' upper barrel assembly you can get a new caliber, change the carry handle to an optics-ready flattop receiver, and have a rifle that compliments your shooting and hunting style.

No FFL is required for an upper-only purchase and it costs less than a complete rifle.
