The BRN-180

The BRN 180 in 300 Blackout demonstrates impressive performance, particularly when suppressed, as shown in a high-speed shooting montage. The video highlights the integration of the BRN-180 upper with a custom lower, Trijicon MRO optic, and a folding stock. Ammunition preparation using Mark-I Genesis Launch ammo boxes and custom magazines is also featured, showcasing a well-equipped setup for range testing.

This video compares two 300 Blackout rifle builds: one using a Direct Impingement (DI) system with a ROSCO MFG barrel and the other employing a piston system, specifically the Brownells BRN-180. The hosts detail the components, accessories, and rationale behind each build's configuration. Key discussion points include the differences between DI and piston operating systems in 300 BLK, the versatility of the 300 Blackout caliber for both subsonic and supersonic applications, and its suitability for reconnaissance (Recce) roles. The video aims to provide insights for rifle builders and those interested in various operating systems and mission adaptability of the 300 BLK caliber. It also promotes the Barrel & Hatchet community and provides discount codes for various firearm-related products.

The AKB-23 is a new bullpup lower receiver designed for AR-15 based bufferless uppers, aiming to replicate the SA80/L85 form factor. It's constructed from billet aluminum, priced around $800, and compatible with uppers like the Brownells BRN-180, PSA Jackl, and FM-15. Testing indicates good reliability, with production underway.

The A3 Tactical Triad chassis converts bufferless AR-15 uppers into a bullpup configuration, offering a compact alternative. While compatible with many bufferless systems like the BRN-180 Gen 2, it requires specific lower receivers and can face trigger reliability issues, notably with the included Rise Armament RA-140. Upgrading the trigger is often necessary for optimal performance, but the familiar AR manual of arms and compact size are significant advantages.

The Brownells BRN-180 Gen 3 introduces significant upgrades, including a closed system to prevent debris and a left-side non-reciprocating charging handle. It features functional improvements like QD sling points and an adjustable gas system. Pre-release testing showed promising reliability, with only one malfunction in 400 rounds.

This video focuses on the Brownells BRN-180 Gen 3 firearm. As a review or informational piece, it's expected to cover the features, performance, and potential applications of this specific rifle variant. Viewers can anticipate details about its design, build quality, and how it handles during range testing. The content aims to inform potential buyers or enthusiasts about what the BRN-180 Gen 3 offers within the modern sporting rifle landscape.

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.
