This guide provides 17 essential habits for maintaining military surplus rifles to ensure longevity and reliability, even beyond 10,000 rounds. It covers proper cosmoline removal, immediate cleaning after corrosive ammo, judicious lubrication, environmental storage controls (humidity and temperature), wood stock conditioning, and proactive part replacement. Following these disciplined maintenance practices, similar to those used by military armorers, is crucial for preserving these historic firearms.

This ARFCOM News segment discusses the 8th Circuit Court's decision to overturn the US v. Brad Wendt machine gun conviction, potentially making machine guns 'great again' by challenging the application of certain statutes. It also critically examines high-pressure ammunition claims and explores a controversial Oregon initiative to ban hunting and fishing. The video features an authoritative speaker with deep knowledge of firearms law and ballistics.

This video from TheYankeeMarshal, featuring Pete Garr, addresses the user's question about standards for +P and +P+ ammunition. While +P has defined standards, +P+ does not, creating potential dangers. The speaker, exhibiting experienced authority, highlights the risks of exceeding pressure limits and points to handloaders as a source for detailed pressure data.

This video clarifies the differences between .223 Remington and 5.56 NATO ammunition, primarily focusing on chamber pressure and chamber dimensions. It emphasizes that while similar, 5.56 NATO operates at higher pressures (around 58,000 PSI) compared to .223 Remington (around 55,000 PSI). The instructors strongly advise against firing 5.56 NATO in a rifle specifically chambered for .223 Remington due to potential catastrophic failure, while noting that .223 Remington is generally safe to fire in 5.56 NATO chambers.

This guide, presented by an experienced firearms instructor, details how to diagnose and fix AR-15 gas system issues. It covers identifying overgassed and undergassed symptoms through brass ejection patterns and provides mechanical solutions like adjustable gas blocks, buffer swaps, and BCG upgrades. The instruction emphasizes understanding dwell time and unlock angles for optimal performance, especially with suppressors.

This guide explains the meaning of '+P' on ammunition, emphasizing that it denotes higher pressure loads due to increased powder content. It stresses the critical importance of verifying firearm compatibility with +P rounds to prevent catastrophic failure and injury. The information also touches on performance trade-offs and considerations for short-barreled firearms.

This video details the US military's XM9 trials in 1984, where the Beretta 92SB-F (later M9) was selected over the SIG Sauer P226 and the M1911. It highlights the rigorous testing, cost analysis, and subsequent legal battle initiated by Beretta against the US government for defamation. The narrative also touches upon the issues that led to the M9A1 and the FS variant, primarily stemming from the misuse of '+P+' ammunition by Navy SEALs, which caused slide failures.

Chris from Regular Guy Training LLC discusses common gear failures, emphasizing blind brand loyalty as a primary cause. He advocates for rigorous testing over brand reputation, highlighting issues with specific products like Magpul accessories and the Sig Sauer P320. The discussion also covers essential firearm recommendations, training methodologies, and the nuanced role of suppressors, stressing practical application over perceived necessity.

This video demonstrates a controlled test simulating a barrel obstruction in a Thompson/Center Encore rifle barrel. The process involves firing a standard round into a deliberately obstructed barrel to observe failure modes. The objective is to ensure the firearm design prioritizes shooter safety by containing damage to the gun itself, even under extreme pressure events. The test highlights how the barrel material should peel back rather than fragment.

This guide emphasizes the critical importance of matching modern ammunition to vintage firearms. It highlights specific examples like the M1 Garand, .22LR pistols, and .32 caliber revolvers, detailing how higher pressures or velocities from modern rounds can damage these older firearms. The advice focuses on using ammunition specifically designed for vintage firearms or understanding pressure limitations to prevent damage and ensure safe operation.

This video debunks the myth that Ruger firearms are inherently stronger than Smith & Wesson. The instructor explains that direct comparisons must be 'apples to apples' (similar size/class) and that perceived differences in strength are often due to manufacturing processes (casting vs. forging) or simply larger firearm models. The core argument focuses on 'efficiency ratings' of firearms, explaining how variations in tolerances, chamber throats, and barrel throats can affect how much energy a specific round produces within a given firearm, thus determining safe ammunition usage rather than absolute firearm strength.

This podcast episode features a discussion on various firearms topics, including the Ruger LCRx revolver for pocket carry, the durability of Ruger firearms compared to Colt and Smith & Wesson, and the mechanics of revolver cylinders. The host also touches on personal experiences with firearms, such as accidental shootings and the importance of proper training. The conversation delves into the technical aspects of firearm design and the historical context of ammunition pressure limitations.
