This video compares carbon fiber and magnesium AR-15 lower receivers as alternatives to traditional aluminum. The carbon fiber receiver from Tegra is noted for its extreme lightness, while the magnesium receiver from Mag Tactical offers a smoother finish and appears more robust with steel inserts for critical components like the buffer tube and trigger pin areas. The presenter expresses curiosity about the long-term durability of carbon fiber but notes its significant weight savings.
