This video details a 'redneck science' moondust durability test comparing a US-made PSA AK-47 to a previously tested Russian AK. The test protocol involves contaminating the firearm with simulated dust, firing it, and even intentionally dropping components into the dust before reassembly and further firing. The results suggest significant improvements in US-made AKs over the years, with the PSA AK performing comparably to its Russian counterpart in this harsh test.

This video details a "moondust" (fine sand/dirt) test on the HK MR556 A4, a short-stroke gas piston AR-15. The rifle initially performed well with the port cover closed, firing 15 rounds without issue. However, after intentionally contaminating the bolt carrier group with moondust, the rifle began to short-stroke, failing to chamber new rounds. Despite a quick field cleaning, the failures persisted, leading the presenter to express surprise and disappointment.
