Malfunctions Clearances Practices

This video highlights critical firearm safety failures and explains the concept of 'height over bore.' It demonstrates how the difference in height between a firearm's optic and its barrel affects bullet impact, especially at close ranges. The content emphasizes the importance of understanding this principle and adhering to the four fundamental rules of gun safety to prevent accidents.

This guide details how to test propellant temperature sensitivity, a crucial factor for consistent long-range accuracy. It emphasizes using a reliable chronograph and testing ammunition across a wide temperature range, from cold to hot conditions. The process involves calculating the muzzle velocity change per degree Fahrenheit to understand how temperature fluctuations affect performance, enabling shooters to account for these variations in their ballistic solutions.

This guide details the process of zeroing a handgun optic, emphasizing the reduction of shooter error by using a stable rest. It covers firing initial groups, calculating adjustments based on optic specifications, and making incremental changes to achieve a precise point of impact at a recommended 25-yard distance, while acknowledging the impact of environmental factors like wind.

This video from Brownells, featuring Caleb, explores the optimal zero distances for an AR-15, primarily for competition use. It analyzes four common zero distances: 25, 36, 50, and 100 yards, detailing their impact zones on an IPSC A-zone target at various ranges. The instructor emphasizes that the 'best' zero is dependent on the intended use of the firearm and the optic employed, recommending the 100-yard zero as a versatile option for experienced shooters, while suggesting 36 or 50 yards for those using red dots or LPVOs respectively, especially for closer engagements.

This video from GBRS Group explains the ballistic principles of deviation and deflection. Deviation is defined as a projectile passing through an object, while deflection is a contact that disrupts or changes trajectory. The demonstration uses 5.56x45mm rounds impacting pillars to illustrate these concepts, showing how fragments can cause minor disruption without lethal effect.

This video explains the fundamental differences between Minute of Angle (MOA) and Milliradian (MIL) as units of angular measurement used in rifle scopes. It clarifies that MOA is 1/60th of a degree, equating to approximately 1 inch at 100 yards, while MIL is 1/6400th of a circle, equating to 10 cm at 100 meters. The instructor notes that most precision scopes use quarter MOA adjustments, allowing for fine-tuning.

This video provides expert guidance from Instructor Mike on how an Illinois concealed carrier should comply with police during a traffic stop. It details maintaining officer safety, proper disclosure of a concealed firearm, and presenting identification and permits from a lanyard to avoid sudden movements. The instructor emphasizes proactive communication and adherence to safety protocols taught in his courses.

Instructor Mike, identified as a Firearms Instructor, provides expert guidance on secure firearm storage within a vehicle. He strongly advocates for carrying the firearm on your person as the most secure method, with shoulder holsters presented as a viable alternative. The video explicitly discourages several common but unsafe storage locations, including between seats, sun visors, door pockets, near the steering column, center consoles, and glove boxes, highlighting the risks associated with each.

This video from Instructor Mike critiques an off-duty officer's poor tactical choices while working a side job. Key takeaways include the dangers of wearing a hoodie that obstructs peripheral vision and the risks associated with using earbuds that diminish auditory awareness. Instructor Mike emphasizes the importance of maintaining situational awareness even when off-duty or in a secondary role.

This video demonstrates a traffic stop scenario involving Instructor Mike and a Chicago police officer. It highlights the importance of maintaining visible hands during an interaction and provides a practical example of how to communicate effectively with law enforcement. The officer issues a warning for a missing license plate, emphasizing the need for proper vehicle documentation.
