This video provides an expert-level examination of the rare Portuguese Abadie 1878 revolver, detailing its unique single-action and double-action mechanism. The speaker, demonstrating high authority, walks through the firearm's distinctive takedown procedure, highlighting the innovative Abadie system for rapid cylinder manipulation. The review contrasts this solid-frame design with contemporary top-break revolvers.

Hickok45 explores the Smith & Wesson top-break revolver, specifically the Model 3 and Schofield variants, explaining their historical prevalence in the Old West was often overshadowed by the Colt Single Action Army in popular media. He demonstrates the Schofield's .45 Colt performance on a private range, highlighting its unique top-break action and automatic ejection.

This video explores the Herman Brevete Handlebar Pepperbox, a unique 6-shot, 5mm pinfire revolver designed for concealment in bicycle handlebars. While historically interesting and featuring a clever detachment mechanism, its practicality for modern concealed carry is questioned due to security risks. The firearm utilizes a double-action mechanism and a split central arbor for cylinder removal and ejection.

The Modele 1886 Lebel is highlighted as the first military rifle to adopt smokeless powder, a significant advancement that dramatically increased firearm range and velocity. Despite French efforts to maintain secrecy, the technology was reverse-engineered by other nations. A design constraint led to a double-tapered cartridge, which proved to be a long-term flaw.

This video features firearm expert Jonathan Ferguson examining two unique mid-19th century self-defense pistols equipped with spring bayonets. The discussion delves into the weapon's design, revealing the locking mechanism and the integrated bayonet. The episode, marking the last of 2022 for the #WhatisthisWeapon series, highlights obscure historical arms and expresses gratitude to supporters, with a promise of more intriguing objects in the new year. The Royal Armouries, the UK's national collection of arms and armour, presents this behind-the-scenes look at their collection and encourages viewer engagement.

Hickok45 reviews a modern replica of the Henry 1860 lever-action rifle, comparing its loading mechanism to the Winchester 1892. He demonstrates the unique, albeit cumbersome, method of loading the Henry 1860 by sliding a follower tab and rotating the magazine end cap. Despite its quirky design, the rifle proves accurate and functional on the range, though historical design flaws like the lack of a handguard are noted.

This video details the unique 'French Finger Trap' issue with the MAS-36 rifle's bayonet, where two rifles can become unintentionally locked together. A 1951 French arsenal memorandum identified this problem, proposing a simple modification to the bayonet handle. Drilling a small hole allows a tool, like a firing pin, to depress the internal spring, enabling the separation of locked rifles.

The M134 Minigun is a scaled-down 7.62 NATO rotary cannon, requiring 24V DC power and consuming 1.5 kW. Its high rate of fire (3,000+ RPM) is essential for aircraft engagement windows. The complex delinker mechanism is critical for feeding ammunition, and practical hand-held use is impossible due to weight and recoil. Live fire demonstrates rapid ammunition consumption and the need for indirect aiming.

The H&K G11 is a revolutionary prototype assault rifle designed in the late 20th century, notable for its caseless ammunition and unique rotating drum bolt mechanism. Despite advanced features like a 2000 RPM burst fire rate and integrated optics, its development was ultimately halted by geopolitical shifts and cost concerns.

This video demonstrates the assembly and live-fire of the German 1936 pattern light mortar (L.Gr.W.36). It highlights the mortar's leveling mechanism for accuracy and the difficulty in visually tracking its 50mm projectiles after firing. The content showcases historical military hardware and its operational use.
