This guide details the proper procedure for zeroing a rifle for combat engagements. It emphasizes correct optic mounting, grouping to confirm fundamentals, understanding bullet drop compensators, and choosing between a 25-meter or 50-meter zero based on expected engagement distances. The instructor stresses the importance of confirming the zero at range and avoiding common mistakes like resting the barrel on supports.

This video features an interview with Ryan McBeth, a former anti-tank and heavy weapons infantryman, discussing the performance of commercial AR-15 rifles and their suitability for export to Ukraine. Key takeaways include the significant performance difference between 1:9 twist barrels and faster twists (1:8 and 1:7), with 1:9 being deemed inadequate for modern ammunition. The discussion also delves into the nuances of rifle zeroing, debunking the common trope of a 25-meter zero being perfectly aligned with the muzzle at 250 meters, and highlighting the importance of understanding bullet trajectory and stabilization.

This guide details how to effectively zero an AR-15 platform rifle at 25 meters using Rite in the Rain's specialized all-weather targets. The targets feature clear windage and elevation adjustment grids tailored for both M4 carbines and M16A2/A4 rifles, simplifying the process of achieving a 300-meter effective range zero. The waterproof nature of the targets ensures durability and usability in any weather condition, making them a valuable tool for consistent marksmanship training.

This video provides expert recommendations on rifle zero distances for WROL/SHTF scenarios. The instructor, with 12 years of training experience, critiques common zero distances like 100 meters (deemed useless) and 36 meters (acceptable but not ideal for longer ranges). He strongly advocates for a 25-meter zero confirmed at 300 meters as the most versatile option, allowing for effective engagement from 0 to 600 meters with modern optics. A 50/200 meter zero is presented as a viable alternative specifically for urban or CQB environments.

This guide details a practical 'rough and fine' zeroing technique for the Discovery HD 3-12x44 SFIR scope, demonstrated by the presenter. It emphasizes aligning open sights with the scope's reticle for an initial zero, then using bullet impact to make precise adjustments via the turrets. The method includes setting the scope to zero after achieving accuracy at 25 meters.

This video offers a highly critical, historically grounded analysis of the M14 rifle's shortcomings, attributing its failure to flawed US Ordnance Corps decisions regarding cartridge standardization and weapon design. The speaker, an expert in small arms, details how political motivations and resistance to innovation led to the adoption of an inadequate weapon system, contrasting it with superior alternatives like the AR-10 and FN FAL. The analysis highlights the detrimental impact of these decisions on US military effectiveness, particularly in Vietnam.

This expert-level entry details the M16's troubled introduction in Vietnam, debunking myths of inherent design flaws. It highlights how political decisions, procurement issues, and ammunition choices, rather than the core design by Eugene Stoner, led to early reliability problems. The entry emphasizes the mechanical evolution from the AR-15 to the M16A1 and the critical role of chrome lining, proper maintenance, and correct ammunition in establishing the platform's eventual success.

This guide, drawing on the expertise of a former Colt employee and AR-15 SME Hank Tatro, details the critical role of AR-15/M16 buffers. It explains how buffer design evolved to manage bolt carrier bounce caused by increased firing rates and different ammunition types. The guide emphasizes selecting the correct buffer for specific firearm configurations and warns against improper mixing and matching, particularly for duty applications. It covers standard rifle and carbine buffers, as well as H, H2, H3, and specialized 9mm buffers, providing insights into their construction and application.

This comprehensive review by Chris Bartocci, a recognized expert with extensive military armory experience, debunks common myths surrounding the Beretta M9/92FS. Bartocci details the pistol's history, including its selection over the M1911, and addresses controversies like slide failures, attributing them to ammunition and high usage rather than design flaws. He highlights the evolution of critical components like the locking block and discusses magazine reliability issues, offering practical insights for owners and enthusiasts.
