The PKM (the worlds best machine gun?)

This video provides an expert-level comparison of the Combloc RPD and PKM machine guns, highlighting their distinct design philosophies and operational features. The host, demonstrating high authority and hands-on experience, details the RPD's milled receiver and AK-like operating system versus the PKM's stamped steel construction and lighter feel. Key differences in caliber, charging handles, and barrel systems are thoroughly explained.

This guide details the quick-change barrel procedure for the PKM, a critical feature for sustained fire operations. The video highlights the PKM's lighter weight compared to the M240B and its open-bolt system, which aids cooling and prevents cook-offs. Instruction is provided by recognized subject matter experts, offering a high level of authority.

This guide details a comprehensive testing methodology for specialized ammunition, specifically focusing on a detonator-loaded bullet. It outlines a step-by-step process for evaluating its performance against various targets, from soft tissue simulants to hard materials, using standard FMJ rounds as a baseline. The expert-level approach emphasizes meticulous documentation, velocity measurement, and analysis of impact effects to understand the unique destructive capabilities of such ammunition.

This video from Edwin Sarkissian showcases various machine guns and firearms, including the PKM, AK-47, M60, and M16, firing tracer ammunition. The expert firearms content creator demonstrates the visual effects of tracers, their performance, and highlights critical safety concerns, particularly the significant fire hazard associated with their use. The content emphasizes practical firearm handling and responsible range operations.

This video appears to be a ballistic test comparing the effectiveness of body armor against 7.62x54R PKM rounds. The title explicitly mentions "Coletes à prova de bala vs munição perfurante 7,62 PKM" (Bulletproof vests vs 7.62 PKM armor-piercing ammunition) and promises a "surprising result." This suggests a demonstration and analysis of penetration capabilities, likely featuring live-fire testing.

This entry provides an expert overview of the Dragunov SVD, detailing its design origins in the 1960s as a Soviet DMR. It covers its semi-automatic, gas-operated mechanism, 7.62x54R caliber, and standard PSO-1 optic with an 800-yard effective range. The information highlights the rifle's enduring legacy and its various international variants.

This guide details the proper technique for safely loading the M1 Garand, specifically addressing the common 'Garand Thumb' phenomenon. It emphasizes maintaining downward pressure on the en-bloc clip during loading to prevent the bolt from slamming forward prematurely. Expert instruction from Garand Thumb highlights this as a key safety measure for new shooters.

This comprehensive review of the Russian Altyn helmet, presented by Garand Thumb, details its construction and ballistic performance. The helmet features a 3mm titanium shell with an aramid liner, rated for pistol and fragmentation threats. Testing reveals it stops 9mm and .44 Magnum rounds but fails against rifle calibers like 5.56x45mm and 7.62x39mm. Despite its robust construction for its intended role, its significant weight and lack of rifle protection are noted as drawbacks compared to modern alternatives.

Garand Thumb, a recognized subject matter expert in tactical equipment, critically assesses the effectiveness of ballistic face masks. The video details rigorous testing using realistic ballistic dummies and various firearms, from handguns to rifles, to measure projectile stopping power and backface deformation. The conclusion highlights significant risks associated with these masks, primarily due to severe deformation, suggesting they are often 'gimmicky' and less effective than traditional head protection.

This guide details the correct technique for loading the M1 Garand rifle, specifically addressing how to avoid 'Garand Thumb.' It emphasizes the 'bladed hand' method, a crucial technique for safe and efficient loading demonstrated by the speaker. Proper execution involves a swift, decisive motion to seat the en-bloc clip while protecting the thumb from the forward-moving bolt.
