The PKM (the worlds best machine gun?)

This video from Shot Show 2026 provides an in-depth look at new and surplus firearms from Zastava Arms USA. Key highlights include discussions on M70 parts kits with differing receiver thicknesses, the historical significance of trench art on surplus rifles, and the functionality of Zastava's grenade launching spigots. The review also covers the M57 surplus pistol, a new M90 configuration with a pinned and welded flash hider, a .300 Blackout M85 variant, and the highly anticipated semi-auto M84 (PKM). The information is presented by Ranko, a representative with deep knowledge of Zastava products and history.

This video provides an expert look at the semi-automatic Zastava M84 PKM, a firearm based on the Russian PKM design, chambered in 7.62x54R and featuring a heavy barrel. It also highlights the Zastava AK Suppressor, claimed to be the lightest and quietest in the U.S. based on Pew Science testing, with compatibility across several Zastava models. The firearm is currently awaiting ATF approval for the U.S. market.

This video provides a detailed comparison between the Soviet RPD and PKM machine guns. It highlights the RPD's rifle-like ergonomics and AK-inspired internals, contrasting it with the PKM's lighter feel due to stamped construction and its more powerful 7.62x54R caliber. Key differences in features like charging handles, barrel systems, and receiver construction are discussed.

The Negev 7 is an Israeli upgrade to the original Negev machine gun, chambered in 7.62 NATO and introduced in 2012. It features a dedicated belt-fed system, removing the box magazine option of its 5.56 predecessor. The weapon boasts a simplified, manually adjustable gas regulator with distinct 'regular' and 'adverse' settings, designed for ease of use even when hot.

TFB TV's James Reeves and Kaya highlight the top 5 long guns from IWA & EnforceTac 2026. The list features innovative designs like the Schmeisser DRS-9 PCC, the compact Serengeti S-Mini shotgun, the robust Zastava M20 machine gun, Sako's versatile AR platform rifles, and the aesthetically striking Walther RS3 straight-pull bullpup rifle, showcasing a range of modern firearm advancements.

The Zastava M84, a licensed PKM variant, is lauded for its extreme reliability and durability, even enduring 500-round bursts without erosion. Its design allows for easy conversion between tripod and bipod configurations. Modifications like folding stocks and Picatinny rails enhance its modern utility, making it a versatile GPMG with historical significance and combat-proven performance.

This video demonstrates the proper technique for loading the M1 Garand to prevent 'Garand Thumb'. It emphasizes maintaining downward pressure on the top round to control the bolt's cycling. The content debunks the idea that 'Garand Thumb' is inevitable, attributing it to inexperience and improper handling.

The Altyn helmet, a Russian titanium model, is tested for its ballistic capabilities. While effective against 9mm NATO and 00 buckshot, it fails to stop rifle rounds like 5.56x45mm and .308 Winchester. The visor cracks under birdshot impact. Despite its historical reputation, its extreme weight and lack of rifle protection make it outdated compared to modern composite helmets.

This ballistic test by Garand Thumb reveals that NIJ Level 3A rated ballistic masks, while stopping some projectiles, fail to adequately protect the wearer due to extreme backface deformation. Hits from a .44 Magnum caused fatal deformation, and rifle rounds completely penetrated. The conclusion is that these masks are largely ineffective and potentially dangerous, recommending helmets and proper training instead.

This video delves into the notorious 'Garand Thumb' phenomenon, explaining its mechanics and pain level through direct testing. It covers the M1 Garand's history, technical specifications, and proper loading techniques to avoid injury, including the 'bladed hand' method. The content also features novice testing and concludes with advice on training and firearm ownership.
