Height Over Bore Training Tip

This video explains the critical concept of 'height over bore' or mechanical offset when using red dot sights on firearms. It demonstrates how the physical distance between the optic's line of sight and the barrel's bore affects bullet impact, especially at close ranges. The content highlights the need to compensate for this offset by aiming higher to ensure rounds hit the intended point of aim, particularly in scenarios like hostage rescue simulations.

This video explains the critical concept of bore offset in firearms, particularly for close-quarters combat (CQB). It details how the distance between the optic's center and the barrel's center causes bullet impact to be lower than the point of aim at close ranges. The instructor demonstrates an '8-inch rule' for a specific AR-15 setup, emphasizing the need to 'hold over' the target to achieve center-mass hits and avoid low shots. Drills for both torso and headshots are presented, highlighting the necessity of understanding and applying mechanical offset for accurate engagement.

This video explains why shooters might miss close-range targets, focusing on the concept of "Height Over Bore" (HOB). It demonstrates how HOB affects point of aim versus point of impact, especially with red dot sights on an AR-15. The content covers mechanical offset, optic height, and how to zero an AR-15 for accuracy under pressure, offering practical tips for tactical rifle training and shooting under stress. It aims to be a comprehensive guide for AR-15 setup and improving shooting fundamentals.

This video explains the concept of "mechanical offset" in relation to AR-15 rifles and similar firearms. Mechanical offset, also known as height over bore, is the distance between the center of the optic's objective lens and the bore of the rifle. The presenter details how this offset significantly impacts accuracy at close ranges, particularly when shooting at small targets. For a typical AR-15 with a red dot sight, the height over bore is often around 2.5 inches. The video demonstrates that at distances of 10 yards or closer, failing to account for mechanical offset can lead to misses. It provides practical advice on how to adjust aiming points, especially when shooting from cover, and recommends range practice to understand and compensate for this effect.

This expert-level guide from Tactical Rifleman demonstrates advanced iron sight techniques for Close Quarters Battle (CQB). It contrasts traditional sight alignment with a faster, over-the-rear-sight method that enhances situational awareness but requires compensation for height over bore offset at CQB distances.

This video showcases advanced dynamic shooting techniques with the FNH SCAR 17, demonstrating its capability in high-intensity drills. Instruction focuses on speed, accuracy, and recoil control while moving and utilizing vehicle cover. The expert-level demonstration highlights fluid weapon manipulation and rapid target engagement.

This video demonstrates advanced 'running and gunning' techniques with the Heckler & Koch HK416 D. It highlights dynamic shooting drills, including rapid fire on steel targets, movement between cover, and seamless transitions between the HK416 and a sidearm. The content also covers preparation, manual of arms, and emergency reloads while engaging targets from unconventional positions.

This video provides a 10-minute guide to fundamental pistol shooting techniques, focusing on semi-automatic firearms like Glocks. Key areas covered include proper sight alignment, a stable grip for recoil management, a balanced shooting stance, precise trigger control, and basic reloading and malfunction clearing procedures. The instruction emphasizes practical application and self-teaching through discipline and range time.
