Videos tagged with Height Over Bore

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 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 reviews the Phoenix Weaponry optic mount for lever-action firearms, specifically highlighting its application on a Henry SPD Hush chambered in .38 Special/.357 Magnum. The mount allows for the attachment of optics like the Vortex Defender ST, addressing potential height-over-bore issues common with lever guns. The presenter emphasizes the benefits of direct-to-receiver mounting plates for achieving the lowest possible optic height and reducing failure points compared to stacking multiple rail sections.

This video demonstrates the "hammered pairs" drill, a tactical training exercise focused on rapid, accurate fire. The drill involves firing two shots in quick succession, with a slight adjustment to the point of aim for each pair. The emphasis is on delivering effective damage to the target anatomy while maintaining speed, highlighting the importance of understanding "height over bore" for accurate shot placement at varying distances.

This guide details the installation and zeroing process for the Vortex Viper shotgun enclosed micro red dot sight, presented by Caleb from Brownells. It addresses common shotgun optic mounting challenges like varying receiver hole spacing and comb height issues. The video emphasizes proper screw selection, torquing procedures, and a practical method for zeroing with both slugs and shot, highlighting the optic's features like motion activation and multiple reticle options.

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 expert guide from NRA America's Rifle Challenge, featuring Kyle Lamb, details how to zero an AR-15 rifle for various shooting scenarios. It covers initial zeroing at 100 yards, understanding height over bore, and advanced dialing techniques for longer ranges using specific ammunition and scope adjustments. The instruction emphasizes practical application for competition divisions.

Chris from Regular Guy Training explains his handgun zeroing process, emphasizing starting at 3 yards to establish height over bore and windage before moving to the final zero distance (typically 25 yards). He details how to measure and adjust sights, and the importance of understanding personal shooting tendencies for consistent accuracy.

This video critically examines the utility of optic risers on firearms, arguing that many are unnecessary and driven by trends rather than function. The instructor, demonstrating experienced authority, explains that risers primarily increase height over bore without offering significant benefits in speed, accuracy, or situational awareness for most users. He highlights specific products like BCM and UTG risers as more practical options, while heavily criticizing the GBRS Hydra Mount for its cost and questionable design principles, suggesting it's only suitable for niche applications.

This guide details how to perform deployment and accuracy drills with the ZEV Magpul FDP, as demonstrated by Roger Barrera. It covers rapid unfolding, accounting for mechanical offset, and achieving accuracy at distance. Barrera, a recognized tactical gear reviewer, emphasizes practical application and performance metrics, including Bill Drill times.
