This entry details the rare Finnish Civil Guard m/33 Sniper rifle, a highly accurate variant built on the Mosin-Nagant m/28-30 platform. It features a unique, adjustable Zeiss scope mount and was developed for competitive marksmanship. Due to its rarity and combat service, few examples survive today.

Parker from Yee Yee Life conducted an experiment to determine how many Feastables chocolate bars could stop various firearm calibers. The tests ranged from a .22 LR, which was stopped by 12 bars, to a .50 BMG sniper rifle, which completely penetrated over 100 bars and the ballistic dummy. The results highlight significant differences in projectile energy and penetration capabilities across calibers.

This review details the Israeli K98k sniper rifles, focusing on their 7.62 NATO conversion and the unique Wild Heerbrug optics. It highlights ergonomic modifications like raised cheek rests and extended safeties, as well as later Nimrod scope retrofits. The rifles were eventually phased out in favor of semi-automatic platforms after the Six-Day War.

This video provides an in-depth look at 2026's most innovative new firearms, covering a diverse range from pistol caliber carbines to .50 BMG sniper rifles. Expert analysis highlights unique features like Franklin Armory's NRS barrel technology, the revival of the Smith & Wesson Night Guard revolvers, and the compact design of the Victrix Corvo CS. The presentation details technical specifications, calibers, and potential applications for each firearm, offering valuable insights for enthusiasts and potential buyers.

The Våpensmia NM-149S is a Norwegian sniper rifle conversion based on the German Gewehr 98 receiver. It features a modernized 7.62 NATO chambering, a detachable 5-round magazine, and significant modifications to the bolt handle and safety lever to accommodate an optical scope.

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.
