This video details a rigorous torture test on an HK MR556A4 upper receiver kit, focusing on the durability of its non-chrome lined barrel. The test involved firing 2,000 rounds (plus an additional 500 pre-test rounds) in rapid succession, simulating a SOCOM firing schedule, with and without a Dead Air Lazarus 6 suppressor. The firearm experienced zero malfunctions throughout the entire test, and surprisingly, its accuracy improved post-torture test, demonstrating exceptional resilience.
