Quick Tip: The Difference Between Square-Notch & U-Notch Rear Sights

This video from Richardson Precision & Training offers a pro tip on identifying and understanding different types of pistol sights. Instructor Daniel explains the benefits of a blackout rear sight with a colored front sight (like fiber optic or night sight) for faster front sight acquisition. He also covers traditional 'goal post' sights, common on Glocks, and the advantages of red dot sights for speed and ease of use, especially for those with aging eyes. The fundamental principles of sight alignment remain consistent across most iron sight types.

This guide details the proper technique for achieving an accurate sight picture using both peep and Patridge sights, as explained by an expert firearms historian and marksman. It emphasizes focusing on the front sight and using a tangent or six o'clock hold for precise aiming, offering a potentially superior alternative to telescopic sights for many scenarios.

This video debunks the 'bullet rise' fallacy, explaining that bullets do not rise due to aerodynamic lift. Instead, they travel in a straight line until gravity pulls them down. The instructor emphasizes that for typical self-defense distances, factors like Earth's curvature are immeasurable and irrelevant. The focus should be on windage adjustments, as most handguns lack elevation adjustment.

This guide, presented by an experienced instructor from Brownells, details the critical differences in measuring front sights for handguns versus rifles. It clarifies how to adjust iron sights to achieve the desired Point of Impact (POI), emphasizing that front and rear sight adjustments work in opposite directions. Understanding these nuances is key for accurate firearm sight management.

This guide explains how to make open sight corrections by detailing the cardinal rules for adjusting rear and front sights. It emphasizes the importance of sight radius and provides a method for calculating necessary adjustments based on desired impact changes and sight dimensions. The video also covers sight height correction for rifles and handguns when standard adjustments are insufficient.

This guide details how to optimize handgun sight picture under stress, drawing from Travis Haley's expertise. It explains the physiological effects of stress on vision and how the TH1RTE3N sights are designed to mitigate these issues through simplified geometry and specific sight dimensions. The guide emphasizes improving hit probability by understanding sight alignment, binocular vision, and the factors affecting POA/POI. Instruction from a high-authority speaker with deep knowledge of ocular physiology and marksmanship principles is provided.

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.
