This upgraded upper includes our Nickel-Boron Bolt Carrier Group with Titanium Firing Pin and the E3 Arms 13″ Quad rail. All of our uppers are available with the standard M4 Melonite barrel, the Stainless Steel barrel or our Pencil Barrel. We try to keep all varieties in stock. If the one of the barrel choices is not in stock we will build your upper receiver with one of the barrels in stock and notify you. If you require a specific barrel, there may be a delay in building your upper receiver.
