This video delves into the history and design of the Colt SMG, one of the earliest 9mm AR-15 variants. It details how Colt adapted the CAR-15 platform to chamber 9x19mm rounds, utilizing Uzi-style magazines with modifications. The description highlights the firearm's closed-bolt, hammer-fired, simple blowback action and efforts to manage its rate of fire. While acknowledging its moderate sales success for Colt, the video also touches upon its reliability issues and mentions specialized variants like the DoE "briefcase gun" and the DEA suppressed model, noting their limited commercial appeal. The content serves as a historical and technical overview of this niche firearm.
This video features a comparison between the Valmet M78 and the FN-D, both robust machine guns. The discussion highlights key differences such as weight, barrel characteristics, sustained fire capacity, and firing mechanisms (closed bolt/semi-auto selector on the Valmet vs. open bolt/slow/fast auto on the FN-D). Both firearms chambered in similar calibers are evaluated based on their reliability and construction, posing the question of which one an enthusiast would choose. The description also promotes weaponsandwar.tv for firearms history content and links to Patreon and Utreon channels.
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 video delves into the history and technical details of the MKb42(H), the precursor to the iconic German Sturmgewehr. It highlights the rifle's development by Haenel starting in 1938, its select-fire capability, and its chambering for the 8x33mm cartridge. The analysis focuses on unique features like the open-bolt design, the reasoning behind it (preventing cook-offs), and how this differed from later closed-bolt Sturmgewehr models. It also touches upon Hitler's initial rejection of the design and the eventual production of the MKb42(H) as a stopgap measure for the Eastern Front, marking the first combat use of the assault rifle concept.
This video delves into the B&T APC-9, a 9mm PCC designed by B&T owner Karl Brügger as an alternative to the MP5. The description highlights its manufacturing simplicity using an aluminum extrusion receiver and polymer grip, its hammer-fired, closed-bolt operation, and the inclusion of a hydraulic buffer to control rate of fire. The APC-9 is noted for its extensive customization options regarding barrel length, color, and magazine compatibility, setting it apart from the MP5. It has seen adoption by various law enforcement agencies in Switzerland, Europe, and the United States, praised for its reliability, simplicity, and customer service despite not being the cheapest option.
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.
This YouTube video from Hickok45 aims to educate viewers on the fundamental difference between open-bolt and closed-bolt firearms. It promises to discuss and demonstrate these mechanisms, providing clarity on how each type operates. The video is presented in Hickok45's characteristic style, emphasizing firearms safety and responsible gun ownership on his private range.
This video introduces the new DK Productions MP38, an authentic, US-made, semi-automatic-only reproduction of the classic WWII German submachine gun. The reviewer highlights that unlike previous attempts, this clone is a faithful reproduction that fires from a closed bolt. The video also promotes the "Military Arms Channel" (MAC) across various social media platforms like Twitter, Patreon, Utreon, and Rumble, and mentions "Modern Gun School" and "Challenge Targets" with a discount code.
This video explores the fascinating Bechowiec (Beha) SMG, a clandestine firearm produced in small numbers in southern Poland by a young resistance fighter named Henryk Strąpoć during World War II. Strąpoć, who had prior experience building illegal pistols, designed the SMG with creative, albeit unfamiliar, submachine gun features. It's essentially a scaled-up Ruby-type action chambered in 9x19mm, featuring a simple blowback slide, hammer-fired closed bolt, and a complex selective-fire trigger system. The video highlights its construction using repurposed WWI Mauser barrels for 9mm and Mosin Nagant barrels for 7.62x25mm Tokarev. Only one example of this historically significant SMG survives today, housed and deactivated at the Polish Army Museum.
This video features a review and range test of the Heckler & Koch UMP 9 in select-fire. The description highlights the UMP's development as a successor to the MP5, noting its direct blowback system and increased recoil compared to the MP5, especially in .45 ACP. However, the reviewer found the 9x19mm version to be easily controllable and enjoyable to shoot. The video includes mentions of Sellier & Bellot ammunition and promotes the channel's store, Patreon, and Instagram.
This YouTube Short demonstrates the operation of a Heckler & Koch UMP submachine gun on full auto, specifically showcasing how closed-bolt machine guns cycle. The video utilizes the UMP as a visual aid to explain the mechanics in a concise, one-minute format. It also includes links to the creator's other content, social media, and affiliate partners.
This video delves into Heckler & Koch's experimental submachine guns, the SMG and SMG II, developed in the 1980s for the US Navy. Designed to replace the MP5 and optimized for suppressed fire, these hammer-fired, closed-bolt, blowback-operated weapons featured collapsing stocks and vertical front grips. The SMG boasted a complex rear sight for subsonic and supersonic rounds, while the SMG II introduced a velocity-reduction system. Despite their innovative features, the Navy ultimately did not adopt either model, though their development influenced the later UMP program.
