PKM vs. Level IV Plate Armor

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.

In this experimental test, Mr. Madness investigates whether a .22 caliber nail gun can defeat a damaged RTS Tactical Level IV ceramic armor plate. Using a Remington hammer-actuated nail gun and specific power fasteners, the test concludes that the nail fails to penetrate the armor, leaving only a superficial mark. This demonstration highlights the resilience of Level IV armor against low-power projectiles, even from unconventional tools.

This video features a "torture test" of a Level IV Stand Alone Armor plate from Trenton Tactical. The test involves battering the plate with various rifle calibers including 7N6 5.45x39, M855 5.56x45, 7.62x39, and 7.62x54r Steel Core ammunition. The description encourages viewers to check out the product on the Trenton Tactical website.

This comprehensive analysis delves into the enduring legacy and battlefield dominance of the PKM machine gun. Drawing on expert insights from armorers, engineers, and combat veterans, the video explores the PKM's robust design, exceptional reliability, and the potent 7.62x54R cartridge. It highlights the PKM's significant weight advantage over contemporaries like the M240 and its surprising accuracy, making it a formidable weapon system even decades after its inception.

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 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.

The Daniel Defense DDM4 PDW chambered in .300 Blackout is presented as a highly effective modern defensive tool. It features a 7-inch barrel, 20-round capacity, and is shown with accessories like a Trijicon RMR and Surefire Scout light. The .300 Blackout cartridge's utility in a PDW platform is highlighted, despite common misunderstandings, with a live-fire demonstration showcasing its effectiveness.

This video compares the 5.56 cartridge to the more powerful .30-06 Springfield, highlighting the latter's historical use. It features a Remington 742 semi-automatic rifle in .30-06, questioning the classification of traditional firearms as 'assault weapons'. Live fire demonstration showcases the rifle's performance.

This review details the AR-57 upper receiver, a conversion for the standard AR-15 platform chambered in 5.7x28mm. It highlights the unique top-mounted P90 magazine system and a clever downward ejection modification using a cut Magpul PMAG to catch spent brass. The demonstration confirms the effectiveness of this brass-catching hack.

The Ruger Mini-14, chambered in .223 Remington/5.56 NATO, is examined for its 'weapon of war' status. The review highlights its modularity, demonstrated by a quick stock swap from synthetic to wood folding. Live fire shows its capabilities, contrasting its public perception with other firearms.
