This review of the Vector Arms Mini Uzi carbine, presented by Hickok45, details its civilian-legal configuration with a 16-inch barrel to comply with NFA regulations. The video highlights the firearm's history, semi-automatic closed-bolt operation, and shooting performance, noting occasional issues with older surplus magazines. Hickok45 expresses frustration with NFA laws impacting the aesthetics of the firearm, contrasting the civilian version's value as an affordable alternative to expensive registered full-auto Uzis.

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 expert-level entry details the remarkable versatility of the Stoner 63, 63A, and Mk23 series. The design's core innovation lies in a single receiver capable of being configured into numerous weapon types, from carbines to heavy machine guns. It highlights the ingenious dual-bolt system and adaptable feed mechanisms, showcasing significant engineering prowess.

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 expert-level review of the Voere SAM-180, a semi-automatic American 180 variant, delves into its unique firing mechanism. The firearm features a simple rotary safety, operates from a closed bolt, and utilizes ginormous 177-round magazines. The internal firing system is particularly noteworthy for its spring-loaded element and the clever absence of a disconnector, relying on the sear's interaction with a fixed bar to hold the striker until trigger release.

This video details the development of the Uzi submachine gun family, covering the Standard, Mini, and Micro variants. It explores Uziel Gal's initial reluctance to create compact models and how the Ingram M11's adoption by Israeli forces spurred IMI to develop competing designs. The Mini Uzi, introduced in 1978, featured a higher rate of fire, while the Micro Uzi and Uzi Pistol, developed later, utilized a closed-bolt system for improved accuracy, directly competing with designs like the HK MP5.

The B&T APC-9, designed by Karl Brügger, offers a modern alternative to the MP5, featuring fully ambidextrous controls and modularity. Its innovative hydraulic buffer system effectively manages recoil and rate of fire, a significant improvement over early prototypes. The firearm utilizes an extruded aluminum upper receiver and polymer lower, allowing for cost-effective production and compatibility with various pistol magazines.

This video provides a detailed overview of the FN PS90, presented as the civilian legal version of the P90 submachine gun. It highlights the firearm's key features, including its chambering in 5.7x28mm, closed-bolt blowback operation, 16-inch cold hammer-forged barrel with an integrated muzzle brake, and fully ambidextrous design elements like dual magazine latches, cocking handles, and a synthetic thumbhole stock. The description also mentions the availability of 10 and 30-round polymer magazines and details other specifications such as weight, overall length, and trigger features. The video encourages viewer interaction through comments and subscriptions, and directs viewers to a website for more information.

The EROP 1954 was a French prototype submachine gun developed in the mid-1950s, featuring a unique square tube receiver and striker-fired bolt. Despite using modified MP40 magazines and having features like a grip safety and bolt hold-open, it failed French military trials due to a high rate of fire, poor accuracy, and reliability issues. Only a few prototypes exist, primarily in police collections.

The BD-38 is a new semi-automatic, closed-bolt reproduction of the German MP-38 submachine gun, manufactured in the US by DK Productions. It features authentic markings and milled receiver details, differentiating it from the stamped MP-40. While sold as a pistol, it can be converted to an SBR. The firearm is compatible with MP-40 magazines and offers modern safety features, though it comes at a high price point of around $4,000.
