The Winchester Model D, a precursor to the famed Model 70, was an experimental bolt-action rifle developed during WW1. It featured a cock-on-close action, Mauser-style flag safety, and a flush-fitting 5-round magazine. While it didn't see military service, its design elements influenced later Winchester sporting rifles.
The H&K XM-8 was a significant contender to replace the M4/M16, featuring a modular design with multiple barrel lengths and an integrated optic with laser/illuminator. Its AR-180 style gas system and polymer construction with a metal trunnion offered a modern approach. The rifle boasted ambidextrous controls and a unique paddle magazine release, showcasing advanced ergonomics for its time.
The AK Fm/57 was a Swedish paratrooper prototype rifle developed in the late 1950s, based on the Ljungman AG-42 but modernized with a short-stroke gas piston and folding stock. Despite being chambered in 6.5x55mm, it was designed for the eventual 7.62 NATO transition. It competed in trials against foreign designs like the G3 and FAL but was ultimately unsuccessful, with the G3 being adopted as the AK4.
The Stamm-Saurer Model 1913 is a rare long-recoil prototype semi-automatic rifle developed by Hans Stamm for Saurer. Its complex dual-spring system and long-recoil action offered safety but proved too complex for mass production. Only 15 prototypes were made before WWI halted development and Saurer's firearms division closed.
The Samostril Netsch was a bizarre early 1920s Czech prototype automatic rifle designed by Jozef Netsch. It featured a unique gas trap system where a forward-moving barrel shroud cycled the action. Intended as a rifle-machine gun intermediate, it competed in 1923 military trials but failed after limited firing. Despite its failure, 25 were contracted, with many surviving in the VHU Prague collection.
This review showcases the rare HK XM8 prototype assault rifle, highlighting its modular polymer construction and integrated reflex sight. The demonstration includes loading IMI Systems 5.56mm ammunition into a translucent 30-round magazine and performing live-fire exercises at an outdoor range, emphasizing safe handling and the weapon's cycling capabilities.
The WF-54 was a Swiss prototype rifle developed by Waffenfabrik Bern, scaling up the German FG-42 design to fire the full-power 7.5x55mm GP11 cartridge. It featured a closed-bolt firing system, a simplified charging handle, and a folding winter trigger. While only about 10 were made, it represented an iterative step towards the later SIG Stgw 57.
The Colt Model 608 was an early AR-15 variant designed as a compact survival rifle for US Air Force pilots. It featured a unique breakdown design for stowage in ejection seats, a shortened grip, and a 10-inch barrel. While only about 10 were made, it represented an early exploration of the AR-15 platform's versatility beyond standard military issue.
This video introduces the Tinck Arms Perun X17, a .308 caliber rifle presented as a direct competitor to the SCAR 17 and Sig SPEAR. The reviewer, associated with Military Arms Channel (MAC), takes a close look at this prototype firearm, highlighting its potential to challenge established models in the market. The description also includes various social media and support links for MAC, as well as a discount code for Challenge Targets and a mention of the Modern Gun School.
This review details the rare Hungarian 33M prototype bolt-action rifle, a transitional design from the Steyr M95 straight-pull. It highlights the shift towards turn-bolt actions due to cold-weather issues and the retention of the M95's en-bloc clip system. The 33M's complex features, including a unique dust cover and folding buttplate cleaning kit, were deemed too intricate and costly for mass production, leading to its simplification into the 35M and subsequent models.
The Kholodovskii Mosin Nagant was an ambitious prototype aiming to improve the standard M91 rifle after the Russo-Japanese War. It featured significant weight reduction through aluminum components and barrel fluting, along with ergonomic and sight enhancements. Despite its innovative design, it failed field tests due to high production costs and poor performance, ultimately being scrapped in favor of simpler models.
The Winchester Model D, a WWI-era prototype, served as a crucial precursor to the iconic Model 70. Developed by T.C. Johnson, its Mauser-based design was influenced by the Pattern 14 and intended for foreign export as an economy sporting rifle. Despite its advanced features like an aperture sight and cock-on-close action, it was ultimately overshadowed by military production needs and later evolved into the Model 54 and then the Model 70.
