This comprehensive review pits the Sig Sauer MCX Rattler LT in 5.56 NATO, 7.62x39mm, and .300 Blackout against each other. Through ballistic gel tests, speed drills, and long-range shooting, the video provides detailed performance comparisons. The hosts, demonstrating high authority, highlight the strengths of each caliber, with the 5.56 version ultimately earning a preference for its balance of recoil and performance.

This "De-Monetized" episode features a comprehensive look at the iconic Daniel Defense MK18, a 10.3-inch 5.56 rifle. The video showcases various performance tests including speed, draw, accuracy, and shooting through various materials. It highlights the rifle's configuration with a Daniel Defense RIS III upper, FA BCG & Trigger Group, and a Dead Air Lazarus 6 suppressor. The review also mentions the Vortex UHG1 optic and 5.56 NATO ammunition, offering a build list for the MK18 SBR.

This video demonstrates the proper technique for loading the M1 Garand to prevent 'Garand Thumb'. It emphasizes maintaining downward pressure on the top round to control the bolt's cycling. The content debunks the idea that 'Garand Thumb' is inevitable, attributing it to inexperience and improper handling.

The Altyn helmet, a Russian titanium model, is tested for its ballistic capabilities. While effective against 9mm NATO and 00 buckshot, it fails to stop rifle rounds like 5.56x45mm and .308 Winchester. The visor cracks under birdshot impact. Despite its historical reputation, its extreme weight and lack of rifle protection make it outdated compared to modern composite helmets.

This ballistic test by Garand Thumb reveals that NIJ Level 3A rated ballistic masks, while stopping some projectiles, fail to adequately protect the wearer due to extreme backface deformation. Hits from a .44 Magnum caused fatal deformation, and rifle rounds completely penetrated. The conclusion is that these masks are largely ineffective and potentially dangerous, recommending helmets and proper training instead.

This video delves into the notorious 'Garand Thumb' phenomenon, explaining its mechanics and pain level through direct testing. It covers the M1 Garand's history, technical specifications, and proper loading techniques to avoid injury, including the 'bladed hand' method. The content also features novice testing and concludes with advice on training and firearm ownership.
