This video tests the ballistic resistance of a commercial 'quebra-queixo' (likely a type of barrier or target material) against various calibers. It demonstrates how different rounds, from .22 LR to 6.5 Creedmoor, impact and damage the material, with higher calibers causing significant structural failure. The testing highlights the destructive power of common rifle and pistol rounds.

This video from Civilian Tactical compares wood and polymer furniture options for the Riley Defense AK-47. The speaker, identified as a Firearms Reviewer and Content Creator, highlights wood for its classic aesthetics and historical accuracy, while noting potential maintenance issues with moisture. Polymer is presented as the more durable and practical choice for rough use, frequent furniture changes, and potentially lighter weight. The content emphasizes safe firearm handling and practical considerations for AK-47 owners.

This video features Edwin Sarkissian conducting an experimental test on the bulletproof capabilities of various chopping cleavers. Using calibers ranging from .22 Magnum to .45-70 Government, Sarkissian demonstrates how different ammunition impacts affect the cleavers, with higher-powered rounds causing significant fragmentation due to material brittleness. The testing highlights the varying durability of steel grades under high-velocity impact.

This video from Civilian Tactical demonstrates a ballistics test on a Bocce ball using various calibers: .22 LR, 9mm, and 5.56x45mm NATO (including M855 Green Tip). The host, identified as a firearms enthusiast with technical knowledge, shows that while the Bocce ball is resistant to smaller calibers, it shatters upon impact with 5.56 NATO rounds, revealing a cement-like interior. The experiment highlights projectile energy transfer and material failure under ballistic stress.

This video tests the durability of a Russian K6-3 helmet against various calibers of ammunition. The helmet features a removable face shield and is constructed from a combination of plastic and metal components. Testing reveals that while the metal front plate offers some ballistic resistance, the plastic portions are not bulletproof and fail to stop rounds. The face shield is also shown to be ineffective against firearm projectiles.
