Videos tagged with Head Thrust

This video debunks the myth of lubricating ammunition, explaining how it can cause excessive head thrust, increased bolt velocity, and false pressure signs. It highlights that such lubrication can lead to firearm malfunctions, accelerated wear, and issues with case expansion, particularly in semi-automatic and blowback-operated systems. The hosts emphasize addressing underlying firearm issues rather than using lubrication as a workaround.

This guide, drawing on expertise from Brownells, addresses the myth of whether over-lubricating an AR-15 can cause malfunctions. Experts explain that while under-lubrication is typically worse, excessive oil can indeed lead to issues like increased bolt velocity, head thrust, and carbon buildup in the gas system, potentially causing the firearm to seize. Proper lubrication is key to reliable function.
