HEIGHT OVER BORE DRILL

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 demonstrates fundamental shooting techniques for both pistol and rifle, emphasizing proper grip, sight alignment, trigger control, and stance. Instruction is provided on how to achieve a surprise trigger break to minimize flinching and improve accuracy. The session covers shooting a Sig Sauer P365 Macro with a suppressor at various distances and introduces basic rifle handling with a 300 Blackout.

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 video details several rifle training drills focused on improving speed and accuracy, particularly for home defense scenarios. It emphasizes proper loading techniques, magazine seating, sling management, and accurate shooting under pressure, including headshot drills. The instructors, Justin and Trent from T-Rex Arms, share their experiences and insights gained from practical application.

This video addresses common issues when switching from iron sights to pistol optics, specifically the difficulty in finding the dot. It explains how traditional iron sight training, which involves a slightly elevated barrel, creates muscle memory that hinders optic acquisition. The instructor advises a more horizontal presentation to ensure the dot is visible earlier.

This guide details a CQB shooting technique using iron sights, focusing on aiming over the rear sight for improved speed and situational awareness. It explains how this method can naturally compensate for height over bore offset, a critical factor in close-quarters engagements. The technique emphasizes focusing on the front sight post for rapid target acquisition.

This video argues for the necessity of AR/AK platform rifles equipped with 30-round magazines for self-defense. The speaker uses the example of a white supremacist march in Indianapolis to underscore the perceived need for such firepower in civil unrest scenarios. The advocacy is framed within the context of Second Amendment rights.

This video humorously demonstrates a fictional firearm, the 'Nicked Gun,' which fires backward, causing the shooter to be struck by her own projectile. The demonstration highlights an unrealistic and comedic weapon mechanic, visually resembling a Walther PPK with a suppressor. It serves as an example of fictional movie props rather than practical firearm training.

This guide, informed by a firearm reviewer and safety advocate, outlines critical safety measures for open carry. It emphasizes the importance of not open carrying alone, recommending group carry for better situational awareness. The guide also stresses the necessity of using a retention holster to prevent unauthorized firearm removal.

This guide outlines the top three essential upgrades for a civilian's first AR-15: a reliable weapon light for target identification, an optic (red dot or LPVO) for accurate shooting, and a two-point adjustable sling for weapon retention and tactical flexibility. The instructor emphasizes the importance of positive target identification, especially in civilian self-defense scenarios where legal ramifications are significant.
