O fuzil AK mais silencioso do mundo!

This video demonstrates the operation of an RPK, specifically a Zastava M72 variant, highlighting its features and basic use. It covers deploying the integrated bipod for stability, loading a round by manipulating the bolt, and adjusting the iron sights for aiming. The presenter also touches on the use of a Zuk suppressor to reduce sound and muzzle flash, and warns about the suppressor's heat after firing.

This guide demonstrates how to significantly reduce the noise signature of an AK-pattern rifle by attaching a specialized suppressor and employing subsonic ammunition with manual bolt cycling. The Zastava Zhuk titanium suppressor is featured, enabling a 'bolt gun quiet' experience when combined with ammunition that doesn't cycle the action. This technique allows for extremely quiet shooting, emphasizing the difference between the gunshot sound and the impact on a target.

This video showcases three distinct firearms: a Bear Creek Arsenal AR-10 chambered in .308, a Vortzson Tandem Cross Raptor in .22 LR, and a Zastava M72 RPK in 7.62x39mm. The presenter highlights various accessories and components, including a Silven Arms suppressor on the AR-10, a Zastava Zuk suppressor on the RPK, and a Star Strike Triton digital night vision optic on the AR-10. The discussion touches on the cost-effectiveness of .22 LR ammunition and the potential for future builds and reviews.

This guide explains how to use an RPK-style rifle, specifically mentioning the Zastava M72, highlighting its differences from an AK47 such as a longer barrel, fixed stock, reinforced trunnion, and heat dissipation features. It details the deployment and use of the integrated bipod for a stable shooting platform and covers basic operation including chambering a round and sighting. A key safety warning is provided regarding the heat of the Zibook suppressor after firing.

This guide details the installation and operational nuances of the original Soviet PBS-1 suppressor for AK-pattern rifles. Expertly presented by Ian McCollum, it covers the unique 14x1L left-hand threading, the critical function of the rear rubber wipe for cycling subsonic ammunition, and the necessity of specialized 194-grain 7.62x39mm rounds. The guide also touches upon the oversized bore design and specialized rear sights, emphasizing the historical context and engineering behind this iconic suppressor.

This video offers a critical review of the RPK from a firearms instructor and custom builder, deeming it overrated and a poor investment. The speaker highlights the RPK's significant design flaws, such as being front-heavy and having an unstable bipod, while advocating for the superior ergonomics and performance of AR-15 platforms, exemplified by his custom 'RPK of the Homeland' build. He emphasizes that professional training offers better value than acquiring impractical firearms.

This video explores the compatibility of a 50 BMG cartridge with a 12 gauge flare gun. The experiment reveals that while the cartridge fits, the flare gun's mechanism cannot ignite the tough 50 BMG primers. However, it successfully fires a standard 12 gauge blank, highlighting the difference in primer hardness. The content is presented from a hobbyist perspective, focusing on experimental curiosity rather than professional instruction.

This video from Tática Civil, featuring an expert instructor, explains the dangers of firing upwards due to projectile drop and terminal velocity. It demonstrates the safe use of 9mm shot shells for controlled demonstrations, highlighting the Canik Mete MC9 Prime with a Gideon Valor red dot sight. The instructor emphasizes crucial firearm safety protocols.

This guide details an experimental test to debunk the myth that a .50 BMG round passing near a target can be lethal. Using a ballistic mannequin, cardboard indicators, and a concrete backstop, the test demonstrates that a near miss from a .50 BMG round does not impart enough shockwave or air pressure to cause fatal injury, though the projectile itself possesses immense kinetic energy as evidenced by its impact on the concrete block. The test was conducted objectively by an individual with high authority, indicated by their empirical testing methods and proper safety protocols.

This video explores the surprising functionality of a realistic toy shotgun, the M870 by Dart Armory. The presenter tests if it can chamber and cycle real 12-gauge shotgun shells, comparing its operation to a Mossberg 590. The toy shotgun successfully loads, chambers, and ejects real shells, demonstrating a high degree of realism in its mechanical operation.
