The PKM: Why This 60-Year-Old Gun Still Dominates the Battlefield

Ranko from Zastava Arms discusses the M84 machine gun, the Serbian variant of the PKM, at Shot Show 2026. He explains the origin of the nickname 'Ceca,' given by soldiers during the Balkan wars due to the weapon's perceived 'pretty sound' when firing. The M84 is a gas-operated, open-bolt, belt-fed machine gun chambered in 7.62x54mmR.

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 video tests the Armored Republic A2 steel plate against armor-piercing 7.62x54R rounds fired from a PKM machine gun. Initial tests with 5.56 rounds showed no penetration. Shockingly, even multiple hits from the AP 7.62x54R rounds failed to penetrate the steel plate or damage the trauma pad, demonstrating its robust protection.

This expert-level analysis from Military Arms Channel details a rigorous test of RMA Armament's Level IV 1199SC ballistic plates against a PKM rifle firing 7.62x54R ammunition. The assessment focuses on penetration, backface deformation, and edge impact performance, providing valuable insights into the real-world capabilities of affordable, NIJ-certified armor.

This video features Eddie Penney, a former SEAL Team 6 operator, discussing critical combat survival lessons. He explains the 'one extra bullet' philosophy for self-preservation and recounts a harrowing experience where a dropped rucksack jeopardized radio communication, necessitating a dangerous retrieval under fire. The segment highlights the importance of preparedness and the extreme measures taken in high-stakes combat situations, culminating in a B-1 Lancer air strike.

This video details a high-intensity tactical entry scenario, showcasing the use of breaching charges and small arms engagement. The narrative highlights the unexpected and grim discoveries made during the operation, including the realization of a fallen enemy combatant mistaken for a carpet. The speaker, a Special Operations veteran, shares direct combat experience and knowledge of breaching procedures and firearms.

This TFBTV episode identifies the top 5 most reliable firearms across different categories: Glock (handgun), Uzi (SMG), Mauser 98 (bolt-action), Remington 870 (shotgun), and Galil (self-loading rifle). The selections prioritize mechanical simplicity, proven track records, and resilience in harsh conditions, often outperforming more complex designs. The video highlights specific features contributing to their reliability, such as the Uzi's single moving part and the Galil's robust construction.

This review highlights five hilariously impractical firearms for concealed carry. It details the slow, complex loading of black powder firearms, the impractical size of the Mauser C96 and full-size .22 pistols for concealment, and the dangerous accidental discharge flaw in the Type 94 Nambu. The video emphasizes that while historically significant, these guns are unsuitable for modern self-defense.

The Ruger Mini-14 offers distinct advantages over the AR-15, including a lower profile, better stock trigger on modern variants, superior maneuverability with folding stocks, a longer sight radius, and a cleaner piston operating system. Modern Mini-14s also boast improved accuracy (around 2 MOA), cold hammer-forged barrels for durability, and optional all-stainless construction for corrosion resistance. While the AR-15 remains more modular and generally cheaper, the Mini-14 excels in specific areas.

This TFBTV episode reviews five excellent surplus rifles available for under $500, focusing on historical significance and affordability. Featured firearms include the Lee Enfield, Yugoslavian Mauser 98, Swiss K31, MAS 49/56, and a debate between the SKS and Mosin Nagant for the final spot. The discussion highlights unique actions, historical context, and the availability of surplus ammunition.
