Rifle Use in CQB

This guide, presented by DJ Shipley from GBRS Group, details the critical concept of height over bore for AR-15 style rifles equipped with red dot sights. It explains how the physical distance between the optic and the barrel affects point of impact, especially at close ranges. The video demonstrates how to compensate for this offset, particularly when zeroing at 25 yards and engaging targets in CQB scenarios, emphasizing the need for precise aiming adjustments to ensure hits in critical areas.

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 demonstrates a close-quarters battle (CQB) technique for shooting with iron sights, emphasizing a faster method by looking over the rear sight. The instructor explains how this approach improves situational awareness and utilizes the height over bore offset to compensate for close-range aiming, making it effective for engagements within a room.

This video demonstrates two techniques for shooting with iron sights in a Close Quarters Battle (CQB) context. The instructor explains the trade-offs between looking through the larger aperture versus looking over the rear sight, highlighting improved situational awareness with the latter. He also touches on the necessity of aiming high due to height over bore offset at CQB distances.

This video demonstrates an alternative iron sight shooting technique for Close Quarters Battle (CQB) distances. The instructor explains how looking over the rear sight and focusing on the front sight post can improve situational awareness. While this method may cause shots to land high, it compensates for the height over bore offset common in CQB scenarios, especially when compared to red dot sights.

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 a critical safety failure during a holstering procedure, resulting in a negligent discharge. The speaker, a tactical content creator, highlights the importance of proper trigger discipline, noting the shooter's finger was on the trigger during the holstering motion. The incident underscores the necessity of rigorous training to prevent such accidents, especially when wearing tactical gear.

This analysis details an uncommanded discharge event involving a Barrett MK22 (MRAD) sniper system. The rifle fired as the bolt was closed, with the shooter's finger off the trigger. The video highlights a potential mechanical failure, emphasizing the importance of firearm safety protocols and awareness of potential malfunctions even with professional-grade equipment. The expert assessment notes the shooter's high authority level and immediate identification of the safety issue.

This video details a critical safety failure involving an uncommanded discharge of a Barrett MK22 sniper rifle during a military training exercise. The footage, captured from a professional military end-user's perspective, shows the rifle firing as the bolt is manipulated, not the trigger. The expert assessment emphasizes the shock and frustration of the shooter, pointing to a potential mechanical defect and underscoring the paramount importance of firearm safety protocols.

This video from Trench Grenade critically analyzes an unintentional discharge event involving a Sig Sauer P320 during a holstering drill. Using high-speed and slow-motion footage, the channel highlights potential safety concerns with gear and technique, emphasizing the importance of proper firearm handling and holster selection. The analysis serves as a cautionary tale for firearm owners.
