UK Special Forces' M16 Variant: the L119A1

This video focuses on Diemaco/Colt Canada AR platforms, often referred to as the "Great White North" ARs. It showcases various aspects of these rifles, likely including their history, features, and potentially comparisons or modifications. The description also includes affiliate links to related merchandise such as PVC patches, posters, a book on the M16, backup sights, earmuffs, a rifle rest, a military tool, and an armorer's manual, suggesting a comprehensive look at these firearms and their accessories.

This review details the Colt Canada SA20, a civilian clone of the Canadian C7A2 rifle. It highlights key differences from the military version, such as black furniture, semi-automatic-only fire, and the absence of ambidextrous controls. The review also covers technical aspects like the bolt carrier group, integrated upper receiver (IUR), and the effectiveness of the C9A2 flash hider.

This video compares the three main AR-15 operating systems: Direct Impingement (DI), Short Stroke Piston, and Long Stroke Piston. DI is simple but dirtier, while piston systems keep the action cleaner but add complexity. Long stroke pistons offer AK-like reliability but can increase recoil, and DI systems may offer better accuracy due to fewer moving parts.

The L119A2 is the standard-issue rifle for UK Special Forces, manufactured by Colt Canada. It features a monolithic upper receiver for improved accessory stability and comes with options for 10-inch or 15.7-inch barrels. While offering upgrades like Geissele triggers and Magpul furniture, it faces challenges with heat dissipation and cleaning due to its design.

This video details the identification and historical context of Canadian-made Colt M4 carbines (Diemaco/Colt Canada) entering the US civilian surplus market. It highlights key visual and internal markings distinguishing them from US-made Colts, such as grey parkerized finishes, Diemaco forge marks, 'CC' barrel markings, and offset gas key staking. The discussion covers the impact of the 1994 Assault Weapons Ban and the collectibility of these unique LEO trade-in rifles.

The Diemaco SFW is a notable M16/AR-15 carbine variant, originally produced by Diemaco (now Colt Canada). It saw significant use with elite units like the British SAS due to its reliability when Colt USA couldn't meet M4 demand. Key features include a 15.7-inch barrel with a unique accessory sleeve, the Diemaco tri-rail system, a Canadian-preferred thin front sight post, and an Elcan C79 optic. Early models used Weaver rails, and it featured distinctive green furniture and Thermold magazines.

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.
