Your *Record Breaking* 5.56 Is a Blatant Lie

This video compares the terminal ballistics of M193 and M855 5.56mm ammunition when impacting a cinder block. The M855 round, characterized by its steel penetrator tip, demonstrated significantly more destructive power, completely shattering the target, while the M193 caused a cleaner penetration. The comparison highlights the different performance characteristics of these common 5.56mm loads.

This video details a destructive durability test of the Stingerworx Evo Ti titanium suppressor on a short-barreled AR-15. The test aimed to determine the suppressor's failure point under extreme stress, firing 1000 rounds or until catastrophic failure. The test highlights the importance of understanding suppressor limitations, especially with high-rate-of-fire devices like FRTs, and emphasizes that all components will eventually fail.

This video features an expert discussion on three specific gripes with the AR-15 platform. The speaker, demonstrating deep knowledge of firearm mechanics and design, critiques the platform's caliber, manufacturing complexity relative to reliability, and the necessity of its buffer assembly. Despite these points, the AR-15 is ultimately lauded as a 'near perfect platform'.

This guide outlines the methodology for a suppressor durability test, as demonstrated in the video. It details the setup using a 7.5-inch AR-15, a Plan B mount system, and rapid-fire testing. The video highlights the importance of extreme safety precautions due to the high risk of catastrophic suppressor failure, emphasizing that such tests should only be conducted by trained professionals.

This video from GUNBROS critiques the concept of a Pistol Caliber Carbine (PCC), specifically questioning the value of a 5.7x28mm variant. The speaker, demonstrating experienced authority, argues that the core purpose of a PCC is cost-effectiveness and magazine commonality, typically achieved with 9mm platforms. The video contrasts this with 5.7x28mm carbines, suggesting they offer no significant benefit over a 5.56mm AR-15 while lacking the widespread ammo and magazine availability of traditional PCCs.

This guide details the installation and operation of the Silent Steel Compact Streamer QDL suppressor. It covers the differences between QD and QDL attachment systems, emphasizing the QDL's improved security with fewer threads and an additional locking mechanism. The guide also highlights the Gen 3 suppressor's performance benefits, including enhanced sound suppression and minimal back pressure, while noting its discontinuation due to an upcoming QDB system.

This guide provides a step-by-step overview of field stripping the SKS rifle, a process essential for cleaning and maintenance. It covers the removal of major components like the dust cover, bolt carrier group, recoil spring, and gas tube. The information is presented with the authority of an experienced firearms instructor, emphasizing safe handling throughout the procedure.

This video provides an expert analysis of current ammunition supply chain issues, explaining how tariffs, geopolitical events, and material sourcing bottlenecks are driving up costs. The speaker, Boondock Ballistician, details the impact of Section 232 tariffs on steel and copper, propellant production shifts, and the nitrocellulose supply chain. It also highlights how increased demand can spur new primer manufacturers to enter the market.

The Boondock Ballistician reviews the PSA H&R 635, a 9mm PCC inspired by the Colt 635. While praising its comfortable ergonomics, minimal recoil, and clean aesthetics (lacking a forward assist), the reviewer encountered significant reliability issues, primarily attributed to straight-profile Uzi-style magazines. These issues included failure to feed and extract, and difficulty seating full magazines. The video also touches on the historical context of the design, its direct blowback operation, and the utility of the A1 carry handle for optics mounting.

This video provides an in-depth review of the Lee Enfield rifle, highlighting its historical significance and operational advantages. The presenter argues it may be the best bolt-action rifle for its use-case perspective, praising its smooth bolt operation, short bolt throw, and 60-degree bolt lift. It details the rifle's adoption by the British Army, its .303 British caliber, and the use of charger clips and detachable magazines, noting James Paris Lee's invention of the latter. The video also touches on its accuracy potential, including its use for volley fire and anti-aircraft roles, and discusses various historical markings and model variations.
