Quick Tip: Using a Torque Wrench on Firearms
This video explains the proper use of a torque wrench, particularly for AR-15 barrel nuts. It clarifies that while a 90-degree angle is ideal for accurate torque application, minor deviations typically result in only a 4-5 ft-lb difference, which is often within the acceptable tolerance for components like AR-15 barrel nuts. The presenter emphasizes that while not always critical for certain components, maintaining the correct angle is considered best practice.
