Videos tagged with AR Builder Mistakes

This guide from Brownells' SmythBusters debunks the myth that dropping the hammer on an empty AR-15 chamber will inevitably cause damage. While considered bad practice due to potential wear on the hammer and bolt catch, the video demonstrates that high-quality, mil-spec or better components are remarkably durable. Military personnel often perform this action during cleaning, highlighting the robustness of properly manufactured parts. The key takeaway is that while avoidance is recommended, accidental occurrences with quality components are unlikely to result in significant damage.

This video details five common AR-15 build mistakes. It covers accessory interference with the gas block, improper gas block alignment leading to cycling failures, incorrect castle nut torque (40 ft-lbs recommended), over-lapping the upper receiver during lapping, and incorrect buffer tube depth affecting the buffer detent. Addressing these prevents accuracy issues and ensures reliable function.
