Mating a steel receiver to an aluminium chassis creates a critical thermal mismatch. In extreme combat temperatures (-50°C to +40°C), this causes the dangerous "cold bore flyer" (first shot deviation). Competitors attempt to fix this using fragile Devcon resin bedding or by glueing the receiver — flawed methods that crack under tactical stress and are categorically unfit for war. We eliminated this flaw through pure structural engineering. Our steel receivers feature integral metal lugs that ensure consistent chassis contact without bedding. Because of these advanced structural lugs, standard legacy magazines cannot physically fit. Thus, we purpose-built these highly durable polymer magazines to flawlessly integrate with our exclusive receiver geometry.
