AR500 Armor VS M855A1 & M193 (14.5, 16 & 18" Barrels)

This video provides a detailed comparison of several 5.56x45mm NATO ammunition types used by the US Navy, focusing on their terminal ballistics and penetration capabilities. The Mark 255 Mod 1, featuring a compressed copper polymer core, is highlighted for its rapid fragmentation and potential for large wound channels, while the M855A1 is noted for its extreme penetration. The M855 Green Tip and Mark 262 Mod 1 are also tested for comparison.

This video compares the 6mm MAX and 5.56 NATO cartridges in identical 10.5-inch AR-15 platforms. Mike from Sons of Liberty Gun Works presents velocity data for various bullet weights in both calibers, highlighting the 6mm MAX's potential for increased lethality and mechanical robustness compared to 5.56 and addressing perceived reliability issues with the 6mm ARC in an M4 platform.

This video tests RMA Level IV armor plates against various rifle rounds, including .30-06 M2 AP and 5.56 M855A1/M855, following news of the armor losing its NIJ certification. The testing demonstrates that the armor successfully stops multiple rounds, including M2 AP, even after its ceramic structure is compromised, suggesting it exceeds its certification requirements. The presenter, a firearms instructor, expresses continued confidence in RMA armor based on these results.

This video demonstrates a ballistic test comparing M193 5.56x45mm ammunition fired from a 20-inch barrel AR-15 against an AR500 steel plate at 15 yards. The test, conducted by Karl Kasarda of InRangeTV, utilizes a KE Arms KP-15 lower receiver and a Trijicon ACOG optic. High-speed footage captures the projectile impact, providing technical insights into the performance of the ammunition against hardened steel.

This video from InRangeTV demonstrates a ballistic test comparing M855A1 5.56mm ammunition against AR500 armor plate. The test, conducted at 15 yards on an outdoor range, shows the M855A1 round impacting the steel plate, causing significant flexing. A water jug placed behind the armor ruptures upon impact, indicating substantial energy transfer. The demonstration highlights the performance characteristics of both the ammunition and the armor under specific conditions.

This video from Administrative Results provides a practical, albeit informal, comparison of steel versus ceramic body armor. The host, demonstrating high expertise in tactical gear, tests both AR500 steel and Highcom ceramic plates against various rifle calibers using a ballistic gel head to assess secondary effects like spalling. The key takeaway is the significant spalling hazard from steel armor, even when it stops a projectile, leading to a recommendation for ceramic armor for its fragment containment properties.

This guide details how to clear common malfunctions on an AK-74 platform rifle, specifically when heavily fouled with mud. Expert instruction from Karl Kasarda demonstrates advanced techniques for dealing with failures to go into battery, feeding issues, and stuck chambers. The video emphasizes the importance of understanding mechanical tolerances and performing thorough cleaning after such extreme environmental testing.

This guide details the historical method of igniting and deploying 18th-century grenades, as demonstrated by Karl Kasarda of InRangeTV. It covers the preparation and use of a slow match to ignite the external timed fuse of a replica grenade. The video emphasizes that this is a replica and stresses the extreme danger and illegality of handling live explosives.

This guide details the proper application of a Gaza-style or CAT tourniquet, as demonstrated by Karl Kasarda on InRangeTV. It emphasizes initial strap tightness before windlass use for effective hemorrhage control and occlusion. The instruction highlights the importance of securing the windlass and managing patient pain during application.

This guide details the historical loading process for the 1836 Colt Paterson revolver, as demonstrated by Karl Kasarda. It covers the unique disassembly required, the precise powder charge and projectile seating using specialized tools, and the capping procedure. The instruction emphasizes a high level of expertise due to the intricate and period-specific nature of the task.
