New Springfield Echelon: Croatia's Chassis System Pistol

This video provides a detailed comparison of the Springfield Echelon 4.0 FC against its full-size and compact counterparts. The instructor highlights the modularity of the Echelon platform, demonstrating how slides and frames are interchangeable. The 4.0 FC is presented as a hybrid model combining a compact slide with a full-size grip, offering a unique balance of concealability and capacity.

This video highlights Springfield Armory's new COA (Compact Optics Adapter) cut, now available on the Echelon, Prodigy, TRP, and 1911 Operator models. This factory-milled slide allows for direct mounting of specific optics like the Aimpoint ACRO, enhancing the pistols' modularity and readiness for optics.

The Springfield Armory Echelon 4.0FC introduces significant modularity with its serialized Central Operating Group (COG) chassis, allowing for easy grip module swaps without additional paperwork. Its Variable Interface System (VIS) enables direct mounting of most red dot sights without adapter plates, promoting a lower cowitness. This full-size frame, compact slide configuration offers enhanced grip purchase and higher capacity, making it a versatile option for various applications.

This review of the IWI Masada Slim Commander Elite, presented by a firearms instructor from Tactical Considerations, focuses on the significant impact of the Mischief Machine aluminum grip module. The host details improvements in recoil impulse, trigger feel, grip texture, and overall handling, comparing it favorably to a 2011 platform. Technical specifications and value proposition are discussed, along with minor critiques on trigger break and reset.

The Springfield Armory Kuna is a new roller-delayed blowback PCC, manufactured in Croatia by HS Produkt. It features fully ambidextrous controls, a tri-lug barrel, and an adjustable folding stock. While originally designed for military contracts, a civilian version is expected to launch around $1,000-$1,100 in 9mm, with proprietary 30-round magazines.

This expert review of the Springfield Echelon Compact, based on nearly 1000 rounds fired, highlights its excellent design and reliability, including a good trigger and modularity. The instructor identifies a specific 'gaper' flaw in the grip that can impede smooth magazine insertion, particularly with full-size magazines, and offers a technique to avoid this issue. Despite this minor flaw, the Echelon Compact is praised for its value and performance, making it a strong contender for duty or concealed carry.

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.
