Building an Accurate AR15 Part 1: The Upper Receiver

This guide details the installation of various Forced Reset Trigger (FRT) kits and related components for popular firearm platforms like the AR-15, Glock, Taurus TX22, Kriss Vector, and Smith & Wesson M&P. It covers unpacking, component identification, installation steps for triggers and selectors, and a crucial safety check. The video highlights specialized kits from DogWood Armory, emphasizing the need for careful installation on specific models.

This guide addresses a critical quality control issue identified by Shortshot Tony on a new Daniel Defense Mk18 upper receiver: a loose barrel nut. The video demonstrates how a hand-tight barrel nut leads to significant rail wobble. It highlights the importance of proper torque for AR-15 assembly and compares this failure to lower-tier brands, emphasizing the need for robust quality control even on premium components.

This guide details the process of lapping an AR-15 receiver to ensure proper barrel alignment for improved long-range accuracy. Instructor Stephen Caleb from Brownells explains that receiver faces can be slightly out of alignment, leading to barrel runout. The process involves using a specialized lapping fixture and aluminum oxide lapping compound with a drill to create a perfectly flat receiver face. This ensures the barrel seats flush and square, critical for precision shooting beyond 500 yards.

This guide details the installation of the Blackout Defense Dual Barrel Nut System, a unique mounting solution for AR-15 style upper receivers. The system utilizes primary and secondary barrel nuts with dual taper locking to ensure bore centricity and a highly rigid barrel mount. Proper alignment of internal tapers is crucial for optimal performance.

This guide details the process of recycling a worn AR-15 upper receiver, specifically addressing a worn charging handle latch shelf, into a dedicated .22 LR build. It highlights the advantages of dedicated .22 LR components over conversion kits and provides specific product recommendations for barrels, handguards, braces, and bolt catches. The process emphasizes practical repair and component selection for optimal rimfire performance.

This guide outlines the conceptual assembly of the unique XR-86 custom rifle, a project by Wilfred Ellis. It details the integration of parts from an M60, M14, and AR-15, highlighting the custom gunsmithing required to combine these disparate systems into a functional firearm. The process involves careful mating of bolt, gas, and trigger mechanisms.

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.
