Travis Haley, a recognized industry leader, breaks down the biomechanics of an effective handgun grip. He emphasizes moving beyond common, often anatomically unsound, grip theories to adopt a more mechanically efficient technique. By understanding lever principles (Class 1 vs. Class 2) and applying the 'crush the apple' concept, shooters can achieve superior control and leverage, particularly during dynamic movement and weapon presentation.

This guide details the analysis of AR15 Bolt Carrier Group (BCG) coatings and finishes, drawing on extensive experience from Chad Albrecht of School of the American Rifle. It categorizes finishes from best to worst based on mechanical efficiency and dimensional accuracy, highlighting common issues with each type, such as corrosion with chrome, lubrication retention with phosphate, and potential brittleness with improperly treated nitride. The assessment emphasizes how coatings affect gas sealing and component wear.
