This video debunks the myth that lubricating ammunition is beneficial. The host explains that oil on ammunition can lead to dangerous pressure spikes within the firearm due to altered case expansion against the chamber walls. This excess pressure can cause head thrust, damaging bolt lugs, flattening primers, and potentially causing the firearm to over-cycle. The video emphasizes that any feeding or extraction issues should be addressed by fixing the firearm itself, not by altering the ammunition. It advises against lubricating ammunition for any firearm, including for handloaders who should remove case sizing lube.
This video debunks a common misconception about the "M" in US military firearm designations like the M16 and M4. Contrary to popular belief, and despite claims by some gun control proponents online, the "M" does not stand for "military." Instead, Brownells Gun Techs™ Caleb and Steve explain that "M" actually stands for "model," meaning M16 simply refers to Model No. 16. The video also briefly touches on the "AR" in AR-15, clarifying it stands for "Armalite Rifle" and not "assault rifle." This is presented as a myth-busting segment.
This video from Brownells Gun Techs Steve and Caleb debunks the myth that storing an AR-15 with the hammer released (forward/down) is necessary to prevent hammer spring wear. They explain that springs wear out from usage cycles, not static compression. While military procedures like dry-firing an M16/M4 into a clearing barrel are for safety, they don't relate to spring longevity. The technicians clarify that both hammer-forward and hammer-cocked storage methods are acceptable, with Steve admitting to using both. The core takeaway is that the fear of hammer spring degradation from storing the rifle cocked is unfounded.
