MK318 SOST | Ballistic Gel Test

This video provides a detailed comparison between M855 'green tip' and M193 'ball' 5.56x45mm ammunition for realistic self-defense and SHTF scenarios. It analyzes their performance based on projectile weight, velocity, penetration, fragmentation, and barrel length, offering guidance on choosing the appropriate round for different rifle configurations and tactical considerations. The speaker, with extensive military experience, emphasizes practical application over theoretical performance.

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 tests the ballistic resistance of a sledgehammer against various calibers, from .22 LR to .50 BMG. It demonstrates that even smaller rounds cause superficial damage, while larger calibers like 7.62x39mm and 5.56mm create significant dents and fragmentation. The .50 BMG round causes the most substantial damage, but the hammer remains intact, suggesting a high degree of ballistic resistance.

This video explains the Plan B mount system used by Lantac suppressors, specifically demonstrating its compatibility with the Lantac Dragon 556 muzzle brake. The presenter highlights the modularity of the Plan B mount, allowing users to switch suppressors between different firearms that utilize the same mounting configuration. The internal threading of the muzzle brake and subsequent baffles is shown, emphasizing the standardized interface.

This video showcases a Daniel Defense MK18 pistol chambered in 5.56 NATO with a 10.3-inch barrel. The presenter details various attachments, including an EOTech optic, Streamlight Protac weapon light, and an angled foregrip, highlighting the quad rail system and a rubberized grip for enhanced handling. Notably, the presenter discusses the firearm's smooth shooting characteristics and a perceived heaviness in the trigger during adverse weather conditions, suggesting potential environmental impact on AR-15 performance.

This video features a social media experiment where three gun tubers (Ian McCollum of Forgotten Weapons, Karl Casarda of In Range TV, and Administrative Results) independently rank four iconic rifles for militia use: the FN FAL, HK G3, AR-15, and AK-47. The consensus among the experts is that the AK-47 is the superior choice for arming untrained conscripts due to its simplicity, reliability, and ease of maintenance, while the FN FAL and HK G3 are deemed too powerful and complex for such a role. The AR-15 is considered good for trained soldiers but less ideal for a ragtag militia.

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.
