This guide details how to inspect AR-15 Bolt Carrier Groups (BCGs) for critical manufacturing defects, specifically focusing on peening marks and burrs on the carrier rails. Instruction from School of the American Rifle highlights how these imperfections, often resulting from attempts to correct loose carrier key pockets, can cause significant damage to the aluminum upper receiver. Proper inspection is crucial for ensuring BCG longevity and firearm reliability.

Master Gunsmith Jack Rowe demonstrates the technique for bending a shotgun stock using a vise and heat. He emphasizes the importance of over-bending to compensate for wood springback and stresses thorough post-bending cleaning to ensure firearm safety and functionality. This technique is crucial for achieving proper gun fit and improving shooter accuracy, especially for aging shooters.

This guide details the expert process of fabricating a mainspring for an 1812 Springfield Musket, as demonstrated by master gunsmith Mark Novak. It covers analyzing original springs, designing new geometry, shaping and welding spring steel, and critical heat treatment processes including hardening via quenching and tempering in a lead pot to achieve the correct tension and durability. The guide emphasizes avoiding stress risers and ensuring proper material properties through precise temperature control.

This video focuses on the challenging process of fabricating new wood furniture for a Marlin Model 30G pump-action rifle. The description emphasizes that this is not a beginner's tutorial, but rather a demonstration of the difficult methods involved in replacing destroyed forend wood while salvaging the metal slide. The creators highlight the complexity and advise viewers not to attempt the process if they cannot perform at this level. The video also includes a call to action for support via Patreon.

This video details an expert-level repair of a chipped 'toe' on an 1891 Argentine Mauser stock, performed by Mark Novak. The technique emphasizes meticulous wood grain matching, precise surface preparation, and the use of Acraglas gel for bonding. A key reinforcement step involves inlaying a 'dog bone' fastener to prevent recurrence. The final finishing ensures the repair is nearly invisible, showcasing advanced gunsmithing skills.

This guide details the process of glass bedding a rifle to enhance accuracy, as demonstrated by GunBlue490. The technique focuses on creating a stable, consistent interface between the rifle's action and stock, preventing movement during recoil. It emphasizes proper preparation, material selection (Devcon Plastic Steel Putty), and application to ensure a precise fit, ultimately improving barrel harmonics and shot consistency. The speaker, exhibiting high authority, cautions that this is a difficult and time-sensitive procedure.

This video details the installation of a Geissele MK8 Super Modular Rail on an AR-15. Key steps include using a Geissele Reaction Rod for upper receiver stability, proper torquing of the proprietary barrel nut, and secure installation of the gas block and tube. The rail is then slid on and secured with two cross-bolts using a T-handle hex wrench. Final steps involve muzzle device installation and a thorough inspection.

Proper ammunition storage is crucial for maintaining reliability and safety. Avoid storing ammo in cardboard boxes in damp environments, as this leads to moisture absorption and corrosion. Utilize airtight containers like ammo cans and control humidity with desiccants like silica gel packs. Heat accelerates gunpowder and primer degradation, so store ammo at stable room temperatures. Reloading primers are particularly vulnerable to moisture and require strict airtight storage.

This video demonstrates how to upgrade an AR-15's A2 furniture to Magpul components. It details the removal of the A2 grip using a Bondhus hex set and the installation of a Magpul MIAD grip with interchangeable backstraps for improved ergonomics. The process also covers preparing and installing the Magpul PRS stock, highlighting its adjustable features for cheek weld and length of pull.

This video explores the custom Remington 11-87 shotgun used as a prop in 'No Country for Old Men.' The film required a semi-automatic shotgun with a suppressor, a combination not readily available at the time. Prop master Larry Zanoff details how a non-functional, 'homemade' looking suppressor was custom-built for the 11-87, with the iconic silenced sound effect achieved entirely in post-production.
