The Worst Service Rifle Upgrade; The M16A2

This YouTube video, based on its title and description, discusses the M16A2 rifle and claims that its design was a 'downgrade' according to Eugene Stoner, the designer of the original AR-15 platform. The title explicitly mentions the M16A2 and Eugene Stoner, indicating a focus on the history and technical aspects of this specific firearm and its lineage. The description also includes a link to a full video, suggesting a more in-depth exploration of the topic.

This review delves into the history and evolution of the M16A1 and M16A2 rifles, highlighting Eugene Stoner's direct impingement system and the 5.56mm cartridge. It covers initial deployment issues, improvements in the A1 model, the introduction of the M203 grenade launcher with the A2, and the lineage leading to the M4 Carbine. The speaker shares personal experiences serving with the M16A2, including basic training and an unexpected deployment to Afghanistan.

This review delves into the M16A2 service rifle, highlighting its historical significance in the early Global War on Terror and comparing its upgrades over the M16A1. The video tests its ballistic performance with 55-grain ammunition, achieving over 2900 FPS from its 20-inch barrel, and contrasts it with Cold War contemporaries. Despite its age, the M16A2 is presented as a capable platform, with a discussion on its pop culture relevance and the modern retro market.

This review defends the M16A2 against common criticisms by examining its original USMC requirements. Key upgrades over the M16A1, such as a closed-bottom flash hider, reinforced components, and improved sights, are detailed. The video argues the A2's weight and design enhance durability and combat effectiveness, despite the controversial 3-round burst.

This video details the history and technical evolution of the M16A2 rifle, highlighting key changes from its M16A1 predecessor. It covers the adoption of the NATO M855 cartridge, the controversial 3-round burst limiter, and design modifications for durability and accuracy. The content also includes insights from Eugene Stoner himself, offering a critical perspective on the A2's development.

This review focuses on the Elisco Tool M16A1, a Philippine-manufactured variant of the classic Colt design. The video highlights its receiver markings, demonstrating licensed production. It includes a live-fire demonstration showcasing full-automatic capability and discusses the rifle's historical significance and technical specifications.

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.
