Daily Defense Season 2- EP 29: AR-15 Magazine Changes & Malfunction Clearance

This video details the El Presidente drill, a timed shooting exercise focused on engaging multiple targets twice, performing a magazine change, and then engaging them twice again. Instructor Pat Mac emphasizes starting at a manageable pace (around 10 seconds) and gradually building speed, focusing on fundamentals like grip and muzzle control to improve accuracy. He also discusses common malfunctions like stovepipes and the importance of consistent practice.

This guide details an efficient reload technique for the MP5, emphasizing minimal movement and proper manipulation of the charging handle and magazine release. It highlights the differences from AR-15 reloads and stresses ensuring the magazine is properly seated before releasing the bolt.

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 practical, albeit unconventional, shooting technique for the AR-15 rifle. A professional firearms instructor explains how to address muzzle rise caused by unstable shooting positions, particularly when using improvised rests. The technique involves adjusting hand placement on the pistol grip to create a more stable brace, prioritizing shot stability over traditional form.

John Lovell, demonstrating expert-level knowledge of the AR-15 platform, explains the function of the forward assist. This feature is designed to manually drive the bolt carrier group fully into battery when fouling, debris, or other issues prevent it from seating properly. Lovell compares its utility to backup sights, emphasizing its value as a redundancy for ensuring reliable operation, especially in adverse conditions.

This video details the 'Rifle Now Drill,' a demanding shooting exercise requiring shooters to fire 30 rounds from a rifle (one in the chamber, 29 in the magazine) within 13 seconds, followed by a reload and one additional shot. All 31 rounds must impact a specific target area. The drill emphasizes speed, accuracy, and efficient magazine management under pressure, with a focus on maintaining tight shot groups at a close distance.

This guide details the installation of a Geissele MK8 Super Modular Rail on an AR-15 platform. It covers securing the upper receiver, installing the barrel nut, gas system, and the rail itself, emphasizing the use of specialized tools and proper torque specifications. The process requires an intermediate skill level and careful attention to detail for a secure and functional build.

This guide, based on expert instruction from Brownells, details essential practices for proper ammunition storage. It emphasizes using airtight containers, managing humidity with desiccants, and maintaining stable temperatures to ensure ammunition reliability and safety. Proper storage is crucial for preventing corrosion and propellant degradation, especially for sensitive components like primers.

This guide details the process of upgrading an AR-15 from standard A2 furniture to Magpul components. It covers the removal of the A2 pistol grip and installation of the Magpul MIAD Grip and Magpul PRS Stock. The video demonstrates efficient assembly using specialized tools, highlighting the ergonomic benefits and adjustability of the Magpul parts. Instruction is provided by Brownells, a recognized industry authority.

This entry details the creation of a movie prop suppressor for a Remington 11-87 used in 'No Country for Old Men.' Prop master Larry Zanoff explains how the suppressor was designed to look homemade and was non-functional, with sound effects added in post-production. The process highlights the creative problem-solving involved in film armory.
