M855A1 vs Ar500 Armor

This video from InRangeTV demonstrates a ballistic test comparing M855A1 ammunition against AR500 armor. Fired from 15 yards, the M855A1 round significantly impacts the steel plate, causing it to flex and transferring enough energy to instantly rupture a water jug placed behind it. The authoritative presentation highlights the performance characteristics of this ammunition against common body armor.

The Safe Life Defense FRAS offers rifle-rated protection with enhanced flexibility due to its hexagonal ceramic tiles and Dyneema backing. It successfully stopped multiple rifle and handgun rounds, including 5.56mm M855 and 7.62x39mm, while staying within NIJ standards for backface deformation. While effective against common threats, it is not rated for full-power rifle rounds like 7.62x54R.

This video tests the ballistic resistance of Shot Stop's SSB-III-RA2 backpack armor panel, which is NIJ Level III rated, against M855 and M855A1 rounds. The test investigates whether common items like a book or laptop placed in front of the polyethylene armor can increase its protection against these specific rifle rounds, particularly M855A1, which is not typically stopped by UHMWPE plates. A Phantom v642 High-Speed Camera is used for detailed analysis of the impact.

This video from TFBTV tests the ballistic capabilities of the Shot Stop Duritium lvl III+ composite body armor plate. They subject the plate to various rifle rounds, including .223 PPU 75gr BTHP, M855, M193, and M855A1 fired from an 18" AR15, as well as M80A1 fired from an 8" .300AAC AR15. The video aims to demonstrate the plate's stopping power against these common threats.

This video tests an AR500 Armor steel plate against rifle rounds, including 5.56mm and 7.62x51mm. The plate, coated with Line-X for spall containment, successfully stopped initial rounds. However, after multiple concentrated hits in the same area, the steel failed, resulting in a plug being punched through.

Testing demonstrates that AR500 steel armor's spall coating is effective at containing fragmentation. An uncoated plate showed significant spalling, while a coated plate, especially within a plate carrier, effectively stopped fragments. The plate carrier itself also plays a crucial role in mitigating spalling.

This video demonstrates the critical failure of a Bulgarian Arsenal SLR104 AK-74 variant when subjected to a mud test. Despite its platform's reputation, the rifle experienced immediate failures to go into battery, eject, and feed due to mud ingress. Repeated attempts to clear the weapon revealed significant friction and a complete mechanical stoppage, highlighting potential reliability issues under extreme conditions.

This video details the anatomy and historical use of 1700s grenades, focusing on their components like the external fuse and internal charge. It demonstrates the ignition process using a slow match and highlights the safety precautions necessary when handling replicas. The content also briefly showcases the hand mortar as an alternative deployment method for these early explosive devices.

This video provides a detailed instructional guide on applying a Gaza-style tourniquet, emphasizing proper technique for effective hemorrhage control. It highlights the importance of initial strap tightening before using the windlass for occlusion and securing it properly. The content also touches upon patient comfort and potential challenges during application.

This video details the historical loading process for the 1836 Colt Paterson revolver. It covers the unique disassembly required, including removing the barrel wedge and the barrel itself. The process involves setting the cylinder to half-cock, charging each chamber with 20 grains of powder and a lead ball, and using a specialized arbor tool to seat the projectile before capping and reassembly.
