A pistola mais barata que já vi!

This video reviews budget-friendly AR-15 platforms under $650, focusing on Palmetto State Armory (PSA) uppers paired with Guesley components. The instructor highlights the value of PSA's Guesley-integrated uppers, particularly the 16-inch Freedom barreled upper with a mid-length gas system and pinned Guesley gas block, and a 10.5-inch option for AR pistols or SBRs. PSA lowers with B5 Systems furniture are recommended for their durability and value, making complete rifle builds achievable under the $650 target.

This review of the Palmetto State Armory .224 Valkyrie upper focuses on its performance compared to earlier iterations. The .224 Valkyrie cartridge, developed by Federal for the AR-15 platform, aims to extend range. The key difference highlighted is PSA's new 1:6.5-inch twist rate barrel, which the reviewer found to be approximately 0.5 MOA more accurate than the older 1:7-inch twist rate barrels. While sub-MOA groups weren't consistently achieved, solid groups were reported, especially with premium ammunition. The review also touches on the compatibility with standard AR-15 lowers and the need for 6.8 SPC magazines.

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.
