Receiving a massive gun collection: Part 1

This guide details how to address a seized AR-15 upper receiver, a common issue exacerbated by suppressor use and infrequent cleaning. The instructor, with extensive firearms experience, demonstrates a multi-stage approach starting with penetrating oils and progressing to more aggressive chemical cleaners when initial methods fail. The video emphasizes understanding dwell time and the effects of carbon buildup, offering practical solutions for a problem that can render a firearm inoperable.

This guide details how to thread the rear takedown pin detent hole on an AR-15 lower receiver using a 4x40 tap and a set screw. This modification allows for easier removal of components like the end plate and buffer tube without losing the rear takedown pin spring and detent. The process involves careful tapping with cutting oil and a specific technique of rotating and backing out the tap to create clean threads. It also covers trimming the takedown pin spring to accommodate the set screw.

This guide details the process of replacing the stock on a Mauser 98 action, a common modification for sporterizing these rifles. It emphasizes that changing stocks and even barrels (e.g., to .30-06) is a straightforward process, debunking claims that older military surplus rifles cannot be modernized. The process involves removing action screws, fitting the barreled action into a new stock or chassis, and re-securing it.

This guide details the installation of a brass backstrap and plug kit for the Glock 17 Gen 6, designed to add weight and improve shooting dynamics.

The added weight is intended to reduce recoil and muzzle flip, while the backstrap aims to provide a more natural Glock grip.

This guide details a DIY modification to a Streamlight for a Tyrant CNC T.W.S. 365 chassis, focusing on replacing factory paddles with a custom-made, larger paddle. The process involves fabricating a pin from a drill bit, drilling the chassis, angling the chassis for switch clearance, and refining the exterior shape. This modification aims to improve the intuitiveness and ease of hitting the light switch, especially when the light is mounted around a pistol's trigger guard.

This guide details the installation of the Strike Industries modular chassis system for the FN PS90, focusing on improving ergonomics. The process involves disassembling the original PS90 stock and transferring internal components into the new chassis. While offering improved handling and accessory mounting options like a 1913 rail and M-Lock compatibility, it introduces a non-tool-less disassembly for the trigger pack compared to the original design.

This guide, presented by D'Boss Firearms, details how to assess a used shotgun's condition, particularly when a seller claims it's in 'like new' or 'never fired' condition. It emphasizes thorough visual inspection for rust and corrosion, and functional testing of the action, highlighting potential issues like severe rust on a Mossberg 500. The advice comes from an experienced firearms professional.

This video humorously depicts a common gun store scenario where a customer dry fires a Glock 19, praises it, but then refuses to buy it due to perceived prior use and a slightly lower online price.
