Knight's Armament Silent Revolving Rifle

The Knight's Armament Silent Revolving Rifle, or R-Squared, was designed for near-total silence, 1.5 MOA accuracy, and evidence concealment by retaining spent brass. It utilizes a custom sabot cartridge with an O-ring mechanism to seal the cylinder gap during firing, ensuring quiet operation and accuracy. This innovative design addresses unique tactical requirements for covert firearm use.

This video provides an overview of a highly modular AR-15 build, referred to as "The Do It ALL Build." The creator aims for maximum adaptability and discusses various components, including barrel length, muzzle devices, suppressors, optics (main, secondary, and thermal), white light, backup irons, and a "DIRV" system. The video also touches upon helmet modularity and other accessories, suggesting a comprehensive approach to a versatile rifle system. It delves into the build's story and includes mentions of Knight's Armament and a "WHA 14.5" component, hinting at specific firearm models and discussions of reliability and accuracy.

This review details a MK18 Mod 0 resto-mod build by Type A Rifles, highlighting its iconic status and historical context. It contrasts the Mod 0 with the Mod 1, discusses technical challenges like dwell time in short barrels, and compares 10.5-inch to 11.5-inch barrel performance.

The KAC LAMG is showcased as a highly controllable, belt-fed 5.56x45mm NATO support weapon. Its constant recoil system significantly reduces muzzle rise during full-auto fire, enabling effective engagement from various positions, including vehicle egress. The weapon's portability and reliability are highlighted, making it a valuable tool for mobile operations.

DJ Shipley details his 2025 Knight's Armament KS3 carbine build, emphasizing a top-to-bottom approach. Key components include the KAC QDC PRT suppressor for enhanced gas flow and noise reduction, a Modlite with Unity Axon switch, and an Aimpoint T2 paired with a Unity magnifier. The setup also features a GBRS Hydra V2 mount for an NGAL IR device, a Radian Raptor charging handle, and Magpul furniture for ergonomics.

This video details a clone build of the rifle used by MSGT John Chapman, the first MOH recipient captured on video. The build represents an early 2000s Air Force Combat Controller 'Recce' style rifle, featuring a 14.5-inch barrel, Leupold Vari-X III optic, and rare Knight's Armament components. It provides historical context on Operation Anaconda and Chapman's heroism.

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.
