Anderson A3 Flat-Top Complete Upper Receiver w/BCG, RF85 Treated

  • 45997

We are proud to present you with a sweet complete upper from our friends in the USA. Lots of positive reviews on these.

Conveniently comes with the dust cover & forward assist already installed. Featuring M4 feed ramps, this upper receiver is machined to Military Specifications & Standards and can be used with multiple calibers on the AR-15 platform. This upper receiver comes in type III hard coat black anodize for extreme durability. Also featuring an installed dust cover, forward assist, charging handle, & Nickel Boron bolt carrier group. 

Anderson's RF85 is a proprietary metal surface treatment where calcium atoms are deposited in the material. It is not a coating, it is a treatment that is left permanently in the metal. RF85 reduces friction 85% and wears with the metal. Under heat and pressure the calcium nano particles elongate and form a protective barrier that eliminates the need for lubrication. Less friction means less wear. A side benefit is the treated components can be cleaned much more easily with dish soap and water.
