This video details the resurrection of the Colt MARS (Mini Assault Rifle System) program by Centurion Arms. It covers the historical context, the unique 5.56x30mm MARS cartridge, and the intricate process of reverse-engineering and manufacturing these rare prototypes. The expertise of Chris Bartocci and Monty LeClaire highlights the engineering challenges and the platform's potential.

Ian McCollum of Forgotten Weapons provides an expert analysis of the Norinco M305A, an M14 variant chambered in 7.62x39mm and designed to accept standard AK-47 magazines. The review highlights the extensive internal modifications required to adapt the M14 platform for the smaller caliber and different magazine system, noting its recent availability in the Canadian market.

This video provides an expert-level look at the T44 LMG prototype, a unique hybrid combining German FG42 and MG42 components. Ian McCollum details the historical context, design challenges, and mechanical modifications required to create this precursor to the M60. The analysis highlights the intricate gunsmithing involved in integrating disparate weapon systems.

This guide details the two primary methods for converting an Uzi into a machine gun: registered receiver and registered bolt, as explained by an expert instructor. It highlights the legal landscape surrounding these conversions, particularly the pre-1986 manufacturing window in the US and the critical importance of proper ATF registration. The information is crucial for understanding historical firearm legality and modification processes.

This video details the 'chop top' modification for the FN PS90 and P90 platforms by MK3 Firearms. The process involves removing the factory sight structure and machining a custom Picatinny rail directly into the receiver, creating an inset mount. This modification aims to provide a sleeker profile and, crucially, an optimal height for a proper cheek weld when mounting optics, addressing previous issues with mounts being too low.

This video demonstrates a unique bolt removal and installation process for the Fletcher Rifle Works 11/22 receiver, designed for the Ruger 10/22 platform. Unlike standard 10/22 receivers, this design allows for bolt removal from the top, eliminating the need to disassemble the action from the stock and trigger group. The process involves a captured takedown pin and keyed railways for easy access and reassembly.

This guide details the disassembly of the rare Sten Mk4(S) prototype submachine gun, focusing on its unique features for paratrooper use. It covers removing the suppressor, barrel, and internal components, highlighting modifications like the shortened receiver, lighter bolt, and compressed fire control group. Expert analysis from Ian McCollum provides historical context and technical insights into this seldom-seen firearm.

This guide details the installation of a bolt-lock safety, a common police retrofit on German inter-war submachine guns like the Erma EMP. The process involves a three-screw housing and requires precise slotting in both the receiver and the bolt to allow a lever to lock the bolt in the forward, safe position. This modification enhanced safety for police carrying loaded weapons.

This guide details the modifications implemented in the Kholodovskii Mosin Nagant prototype, aiming to improve the standard M91. Key changes include weight reduction through aluminum components and a fluted barrel, enhanced sights, ergonomic bolt and stock adjustments, and improved bedding for accuracy. The video highlights the historical context and reasons behind these design choices, ultimately noting the project's failure due to cost and performance issues.

This video details the experimental British conversion of the M1 Garand to select-fire capability in 1939. Expert Jonathan Ferguson explains the historical context, the 'YSL' nickname, and the significant mechanical modifications required, including milling the receiver and adding a disconnector. Trial results indicated extreme difficulty in controlling automatic fire, leading to the project's discontinuation.

This guide details the technical fix for the M1 Garand's notorious 7th round stoppage, a flaw discovered during mass production. Expert Ian McCollum explains how a specific cut during barrel drilling impacted the guide rib, leading to misfeeds. The solution involved restoring the guide rib through welding and adjusting manufacturing processes, highlighting critical shop-floor insights.

This guide, informed by Brandon Herrera, a recognized AK-47 expert, details the differences between AK stock types (fixed, underfolder, side folder) and the significant receiver modifications required for interchangeability. It highlights practical considerations like magazine clearance and shooting comfort, advising that owning multiple AK variants is often more practical than conversion.
