This expert-level guide from Kyle Lamb of Viking Tactics demonstrates how to effectively zero an AR-15 style rifle without relying solely on dialing the scope for every shot. It covers essential techniques like stable prone shooting, understanding height over bore, and utilizing ballistic data for scope adjustments at various distances. The instruction emphasizes the importance of a solid zero for competitive shooting divisions.
This guide, informed by an experienced firearms instructor, critically examines the utility of optic risers on firearms. It debunks common justifications for their use, such as increased speed or situational awareness, labeling them as 'cope' or 'copy-paste' setups. The content emphasizes personal comfort and application intent as the primary drivers for riser selection, highlighting that many shooters benefit from lower mounts. Specific product recommendations and critiques are provided for brands like BCM and UTG, alongside a strong condemnation of the GBRS Hydra for most users.
Roger Barrera provides an in-depth review of the ZEV Technologies and Magpul Folding Defensive Platform (FDP), a 9mm firearm with a unique folding design. He details its 18-year development, purchase price of approximately $1,700, and performance during range testing. Barrera highlights the FDP's smooth recoil, impressive deployment speed (sub-3-second Bill Drills), and surprising 100-yard accuracy despite its integrated sights and mechanical offset. Critiques include the high price point and potential ergonomic challenges with the manual safety.
This video explores the future of rifle optic mounting, focusing on integrated riser bases that co-mount optics and magnifiers on a single plane. The expert reviewer highlights the advantage of maintaining zero when transferring the optic suite between rifles. It also covers single risers for height and full-length upper risers for enhanced NVG compatibility.
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 guide details the installation and use of the DOT EHS-1 holographic sight, as presented by Shortshot Tony. The optic is noted for its significant height, facilitating fast target acquisition and a comfortable shooting posture. It features a 1 MOA dot with a 65 MOA ring, multiple brightness settings, and a dedicated night vision button, making it suitable for passive aiming with NODs and effective on Pistol Caliber Carbines (PCCs).
Roger Barrera of QVO Tactical provides an expert overview of the new Jacob Grey HEX Pro pistol, launched at SHOT Show 2026. The pistol features a 4.6-inch bull barrel with an integrated compensator and hexagonal crowning. Its optic cut for the Trijicon SRO is designed for minimal height over bore. The trigger exhibits a crisp break and short reset, complemented by an ergonomic hex-patterned grip and ambidextrous safeties, with all parts being billet.
Joel Park, an experienced firearms instructor, explains the practicalities of pistol optic zeroing and close-range aiming. He emphasizes verifying your zero through live fire, understanding height-over-bore for holdovers at distances like 5 yards, and proper zeroing methodology using 7-10 yards for windage and 25 yards for elevation. Park also details optic security checks using witness marks and diagnostic dry fire, and advises aiming center mass on complex targets to avoid penalties.
This video from hickok45 provides an expert look at the evolution of the AR platform by comparing a 1984 Colt AR-15 with a modern Daniel Defense DDM4 V7. It covers key changes like the shift to modular rails, explains technical concepts such as height over bore and gas system differences, and demonstrates the performance of a contemporary AR rifle. The comparison highlights how firearm technology and design have advanced significantly over the decades.
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 from Regular Guy Training LLC provides expert guidance on logical AR-15 upgrade progressions. The instructor emphasizes starting with essential ambidextrous controls, a quality charging handle, and a flash suppressor. He advises against early purchases of plate carriers or laser modules, instead recommending a solid optic with backup sights and a weapon-mounted light like the Holosun AEMS and Streamlight ProTac.
This guide details the installation of a top-mounted red dot optic, specifically an Aimpoint Micro H2, onto a Trijicon ACOG TA02 using the Arisaka T-Rex Arms Micro Mount. It covers the benefits of forward mounting for night vision and improved field of view, along with precise torque specifications for both the optic-to-mount and mount-to-ACOG screws. The process emphasizes an X-pattern tightening method for even tension and level mounting, resulting in a heads-up shooting position.
