Teste de resistência: Red Dot aguenta o tranco?

This video details a 1000-round 'torture test' of the O-Sight SE red dot optic mounted on a Tisas Witness2311 CMX pistol. The presenter, demonstrating experienced authority, followed manufacturer torque specifications and used Loctite to secure the optic. The test concluded with the optic remaining firm and functional, despite significant soot accumulation, highlighting its surprising durability for its $170 price point.

This review of the Osight XR optic, presented by Ben Stoeger, highlights its build quality and performance as comparable to Holosun, despite a lower price point. While generally reliable, a specific issue with screw compatibility on Glock Gen 6 models is noted, requiring aftermarket solutions. The optic offers a solid value, though larger window competition sights like the Holosun 507 Comp are preferred for certain applications.

This guide details a practical modification inspired by competitive pistol shooters who adapted the Aimpoint 5000 for compact use. By removing the unnecessary hollow rear section of the Aimpoint 5000, which was originally designed for rifle ring mounts, shooters could create a more streamlined optic. This user-driven innovation directly led to Aimpoint developing the specialized 'Comp' series for competition and compact applications.

This guide details the installation of an AT3 Tactical Red Dot Sight, emphasizing its RMR footprint compatibility for both pistol slides and rifle platforms. The video showcases its versatility on a Glock pistol and as a backup optic on a rifle, highlighting its utility for close-quarters engagements. Proper mounting procedures are crucial for reliable performance.

This expert guide details the unboxing and initial installation of the Osight SE green dot optic, mounted on a Bul Armory pistol. It highlights the optic's RMSC footprint, user-replaceable battery, and versatile reticle options (2 MOA dot, 32 MOA circle, or combination). The guide emphasizes the importance of using the correct mounting screws provided and includes essential firearm safety protocols for optic installation.

This expert guide, informed by a firearms instructor, details potential issues with the Glock Gen 6 factory optic mounting system. It highlights that the universal cut may not provide optimal stability, leading to optics coming loose, as demonstrated by an O-Site optic failure. The guide recommends considering aftermarket plates like Aris for a more secure, machined fit and outlines steps for troubleshooting and installation.

This video explores the theoretical and practical outcome of loading a 50 BMG cartridge into a 12 gauge flare gun. The experiment, conducted by a hobbyist, demonstrates that while the 50 BMG cartridge surprisingly fits, the flare gun's firing mechanism and primer strength are insufficient to ignite it. The test highlights the significant differences in primer resistance between ammunition types.

This video debunks the myth that shooting upwards is safe, explaining the lethal terminal velocity of falling projectiles. It showcases the Canik Mete MC9 Prime with a Gideon Valor optic and demonstrates the use of 9mm shot shells for controlled, less dangerous demonstrations, highlighting their unique projectile dispersal.

This video debunks the myth that a .50 BMG round passing near a target can be lethal due to shockwave. Using a ballistic mannequin head and a Big Kahuna Firearms Raptor-50 rifle, the test demonstrated that while the .50 BMG round impacted and destroyed a concrete block behind the target, it did not affect the mannequin or the cardboard placed near it. The conclusion is that a near miss from a .50 BMG is not fatal.

This video conducts a destructive test comparing the impact of .22 LR and .50 BMG rounds on a ballistic head model. The .22 LR caused minimal damage, while the .50 BMG completely destroyed the head, highlighting the vast difference in energy and destructive potential between the two calibers. The test also showcases the Raptor .50 BMG upper receiver as an accessible way to experience .50 BMG ballistics on an AR-15 platform.
