This entry details the unique XR-86 custom rifle, a 1986 build by Wilfred Ellis. It masterfully combines components from an M60 (flash hider), an M14 (gas system), and an AR-15 (trigger, bolt, locking system). The AR-15 trigger is notably rotated 90 degrees, and its bolt is integrated with the M14 gas system, showcasing advanced gunsmithing.

This video from School of the American Rifle highlights critical manufacturing defects in AR-15 bolt carrier keys, specifically focusing on rough internal bores. Lead instructor demonstrates how a poorly finished carrier key can cause significant friction, premature wear on components like gas tubes, and operational issues, contrasting a problematic new Colt carrier with a well-functioning older model. The expert emphasizes the importance of a smooth bore for reliable function and longevity of expensive parts.

This guide, presented by an expert firearms instructor, details the benefits and installation of adjustable triggers for platforms like the AR-15. It covers understanding trigger mechanics, adjusting pull weight, reset, and overtravel, and highlights ideal users for these components. The instruction emphasizes safety and practical application for competition and precision shooting.

This guide, presented by School of the American Rifle, details how to identify and replace a malformed weld spring in an AR-15 Delta Ring assembly. A misaligned weld spring can cause the gas tube to be pushed off-center, leading to excessive friction or damage to the carrier key and gas tube. Replacing the faulty component ensures proper gas tube alignment and firearm reliability.

This guide details the process of diagnosing and fixing a significant rail wobble issue on a new Daniel Defense Mk18 upper receiver. The primary cause identified was a hand-tight barrel nut, compromising the stability of the RIS II rail system. The steps involve disassembly, inspection of the barrel nut, proper tightening with an armorer's wrench and torque wrench, and reassembly. This addresses a critical quality control failure that can affect firearm accuracy and reliability.

This guide details the evolution of AR-15 carrier key staking from early 'Gen 1' square staking to modern 'Gen 5' OCKS with serrated heads. It emphasizes proper torque values (vintage 35-40 in-lbs, modern 55-58 in-lbs) and the importance of sufficient metal displacement for screw security. The video, presented by an expert from School of the American Rifle, critiques commercial staking and references historical technical manuals.

This video humorously presents the AT4 anti-tank weapon as a 'truck gun' by 'The Gun Guy Cody'. While not a practical choice for concealed carry or typical self-defense, the video highlights its portability via a built-in strap. The content is satirical, contrasting a military-grade weapon with everyday carry expectations.

This video demonstrates essential steps for preparing an AK-47 style rifle. It covers loading a 7.62x39mm magazine, chambering a round by cycling the bolt, and attaching an AK-style bayonet. The content highlights practical firearm readiness for potential use.

This video showcases a Russian soldier successfully neutralizing an incoming drone with a 12-gauge shotgun in a combat zone. The engagement occurred at an estimated range of 20-30 yards, demonstrating the practical effectiveness of shotguns for drone defense despite prior skepticism. The footage highlights a single, decisive shot.

This video provides a visual overview of U.S. military ammunition, ranging from common small arms like 9mm and 5.56mm to heavy machine gun rounds like .50 BMG. It also showcases larger munitions such as 20mm, 30mm (including variants for the AH-64 Apache and A-10 Warthog), and 40mm autocannon rounds. The presentation highlights the diversity of calibers and their associated platforms.
