Fostech and the Magnesium Alloy AR15 - Insanely light weight!
This video explores Fostech's innovative AR-15 platform, which utilizes a proprietary forged magnesium alloy to achieve significant weight reduction. The presenters highlight how this material, often misunderstood as brittle or flammable, is actually stronger than billet aluminum and allows for a rifle weighing as little as 4.5 pounds without accessories. The discussion covers the evolution of the AR-15 towards lighter configurations and the advantages of Fostech's approach for applications like hunting and general use, emphasizing that mil-spec compatibility is maintained.
