April 2017 Q&A - Part 2

The FNAB-43 is a unique Italian submachine gun from late WWII, featuring a compact design with a folding magazine well and a delayed blowback action. It utilizes a closed-bolt system with separate selectors for safe/fire and semi/full-auto modes. While not widely adopted, its innovative mechanisms offer insight into firearm development during the era.

The vz. 61 Škorpion is a unique machine pistol featuring a hammer-fired, closed-bolt operation and a sophisticated rate reducer. Its folding wire stock and compact design are highlighted, along with its distinct vertical casing ejection. The firearm is praised for its clever engineering and sophisticated design, making it an impressive piece of Czechoslovakian military history.

This video delves into the Interdynamic MP-9, the precursor to the TEC-9, highlighting its simple open-bolt design and selector mechanism. It details the fire selector ('F' for semi-auto, 'A' for auto) and the unique notch safety on the charging handle slot. The explanation of the trigger's internal mechanics, particularly the disconnector's role in semi-automatic fire, showcases the firearm's historical engineering.

The Colt SMG, a 9mm variant of the AR-15 platform, was developed to compete with the HK MP5 for law enforcement. It features a closed-bolt, blowback action, distinct from the AR-15's direct impingement system. Modifications include Uzi-based magazines with AR-style release notches and a bolt hold-open feature, a plastic gas deflector, and upgraded fire control pins for durability.

This Q&A video from Forgotten Weapons delves into the multifaceted world of submachine guns (SMGs). The discussion covers historical aspects like the origins of SMGs and early development, as well as contemporary relevance, comparing them to carbines and PDWs. Various technical aspects are explored, including magazine designs, different operating mechanisms (blowback vs. delayed), caliber choices (.357 Magnum, .44 Magnum, 10mm, .38 Super, .300 Blackout), and trigger quality. The video also touches upon cultural distinctions in firearm design, military adoption, training opportunities, and competitive shooting events related to SMGs.

This YouTube video is a live stream of the popular video game Escape from Tarkov, with a specific focus on the PPSh-41 submachine gun, affectionately nicknamed 'PPSh Daddy'. The description includes links to the creator's Patreon and Instagram, suggesting a content creator engaged with their audience. While the video focuses on gameplay within Escape from Tarkov, the title highlights a specific firearm within the game, indicating a potential interest in its mechanics, modifications, or combat effectiveness.

This video demonstrates the critical failure of a Bulgarian Arsenal SLR104 AK-74 variant when subjected to a mud test. Despite its platform's reputation, the rifle experienced immediate failures to go into battery, eject, and feed due to mud ingress. Repeated attempts to clear the weapon revealed significant friction and a complete mechanical stoppage, highlighting potential reliability issues under extreme conditions.

This video details the anatomy and historical use of 1700s grenades, focusing on their components like the external fuse and internal charge. It demonstrates the ignition process using a slow match and highlights the safety precautions necessary when handling replicas. The content also briefly showcases the hand mortar as an alternative deployment method for these early explosive devices.

This video provides a detailed instructional guide on applying a Gaza-style tourniquet, emphasizing proper technique for effective hemorrhage control. It highlights the importance of initial strap tightening before using the windlass for occlusion and securing it properly. The content also touches upon patient comfort and potential challenges during application.

This video details the historical loading process for the 1836 Colt Paterson revolver. It covers the unique disassembly required, including removing the barrel wedge and the barrel itself. The process involves setting the cylinder to half-cock, charging each chamber with 20 grains of powder and a lead ball, and using a specialized arbor tool to seat the projectile before capping and reassembly.
