How to Zero Aimpoint Sight | Shooting Techniques | Tactical Rifleman

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 focuses on improving pistol shooting fundamentals, emphasizing an athletic stance, proper 'thumbs forward' grip, and precise trigger control. It also touches on advanced techniques like long-range pistol accuracy and specific grip adjustments for revolvers. The content highlights how proper body alignment and mental preparation contribute to enhanced shooting performance across various firearm platforms.

This video by GBRS Group focuses on automating firearm safety manipulation for consistent performance. It highlights the importance of engaging the safety every time the firearm breaks the plane and addresses common errors like forgetting to disengage the safety during drills. The instruction emphasizes maintaining thumb tension on the safety lever for a fluid, integrated motion during presentation and reloads.

This basic marksmanship course, led by instructors from GBRS Group, emphasizes a structured approach to skill development. Key takeaways include the critical importance of a proper firearm zero, practicing diverse shooting positions (standing, kneeling, prone), and engaging various target sizes. The curriculum logically progresses through drills, incorporating buddy shooting and barricade utilization to build a comprehensive foundation in marksmanship.

This YouTube Shorts video provides a concise guide on how to zero a red dot optic. The focus is on practical application and ensuring the firearm is sighted in correctly with the red dot sight. It's geared towards firearm owners looking to properly set up their weapon for accurate shooting.

In close-quarters combat, drawing a pistol can be dangerous as an opponent can easily grab the firearm. A tactical knife offers a safer alternative, allowing the user to create space by targeting vital areas like the carotid artery or kidneys. This space allows for a safe transition back to a firearm. The video demonstrates this strategy using a Glock pistol and a fixed-blade knife.

This video details crucial footwork techniques for Navy SEALs during Close Quarters Combat (CQC). It emphasizes 'economy of motion' and the 'long step' technique for balanced entry into corner-fed rooms, ensuring immediate engagement capability. Proper footwork prevents exposing vulnerable side plates and maintains a stable shooting platform.

This video demonstrates a clever modification of standard military cloth bandoliers to increase their magazine capacity. By releasing a hidden white string, the pockets expand, allowing them to hold one or even two 5.56mm magazines each. Special Forces operators pack these expanded bandoliers with other essentials for rapid emergency resupply in the field.

This ballistic gel test compares 9mm Barnes TAC-XPD and .45 ACP Cor-Bon Pow'RBall. The 9mm achieved deeper penetration (13-14 inches) with consistent expansion, while the .45 ACP created a larger wound cavity and significant energy transfer but slightly less penetration. The Cor-Bon Pow'RBall's design enhances feeding reliability in 1911 platforms.
