Active Shooter Backpack Armor: Can M855A1 Defeat Plastic Armor ~AND~ A Book?

This video features a comprehensive ballistic test of the Safe Life Defense Flexible Rifle Armor System (FRAS) by Kentucky Ballistics and Tactical Rifleman. The FRAS, rated for Level III threats, successfully stopped common rifle rounds like 5.56mm M855 and 7.62x39mm. However, it was penetrated by higher-performance rounds such as the M855A1 and .224 Valkyrie, highlighting the limitations of its rating against advanced threats. The testing demonstrates the armor's capability against standard threats while also defining its performance boundaries.

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 provides a comprehensive test and review of the RMA Armament Gen2 1165 RF3 rated lightweight armor plate. The reviewer, with extensive experience in wearing armor, conducts rigorous ballistic testing against various calibers including 300 Win Mag, M80A1, M193, M855, 7.62x39, 10mm, and 9mm. The plate demonstrates impressive performance, stopping all tested rounds initially and showcasing its edge-to-edge protection, though it eventually fails after significant compromise.

This entry details the performance characteristics of the M855A1 5.56x45mm NATO round, as analyzed by Dirty Civilian. The analysis focuses on terminal ballistics in ballistic gel, highlighting expansion and fragmentation patterns. Key technical insights include its higher operating pressure (+10,000 PSI) and its design objective to achieve higher velocities from shorter barrels.

This video details a comprehensive ballistic testing of the Premier Body Armor Fortis Level III+ GT plate, a NIJ RF2 rated armor designed as a lightweight alternative to Level IV plates. The testing involves multiple rifle caliber threats at close range (25 feet) and extended distances (100 yards), evaluating penetration and back face deformation. The plate demonstrates impressive performance against common threats like 5.56x45mm and 7.62x39mm, while also showing its limitations against higher-level threats at longer ranges as expected.

This video features Shortshot Tony, a tactical gear reviewer, conducting live-fire ballistic testing on AR500 steel plates to assess the effectiveness of spall coatings. The experiment demonstrates that while uncoated plates can produce significant spalling, a spall-resistant coating, especially when used within a plate carrier, effectively contains fragmentation.

This video features a critique of a home defense AR-15 build by former Navy SEAL Jeff Gonzales. Key takeaways include the importance of a suppressor for indoor use, the critique of an overly complex sling, and recommendations for reliable optics. The discussion highlights the trade-offs of short-barreled rifles (SBRs) for home defense and emphasizes practical gear selection over complexity.

This guide details the tool-less field stripping process for the Beretta ARX-160, as demonstrated by a Beretta factory representative. It covers the quick-release barrel, stock, trigger group, and bolt assembly, emphasizing ease of maintenance. The representative highlights the rifle's modularity and ambidextrous features, noting its current military availability with future civilian plans.

This entry details the Fostech .50 Cal Drum Magazine, designed for Barrett M107 and 82A1 rifles, featuring a 20-round capacity and billet machined aluminum construction. It also touches upon the Fostech Rader .308 rifle. The information is presented with high technical focus from a manufacturer representative.

This video from ARFCOM News details a ballistic gel test of Remington's 158gr SJHP .357 Magnum ammunition fired from a 16-inch Rossi Model M92 carbine. The test highlights how carbine-length barrels significantly enhance .357 Magnum performance, achieving velocities comparable to some .300 Blackout loads and demonstrating substantial penetration and expansion in ballistic gel. The analysis touches on terminal ballistics theories and the unique behavior of high-velocity pistol rounds fired from rifles.
