This review of the Green Mountain 12.7" AR-15 barrel highlights its lightweight profile and budget-friendly nature, suitable for general use. While the barrel exhibits minimum spec chamber and throat dimensions, its performance is significantly hampered by an oversized gas port, leading to an overgassed system and poor shooting experience. Accuracy varied considerably with different ammunition types, with match-grade loads performing better than M193.

This video from Regular Guy Training LLC details the concept behind the Rare Breed FRT-15L3, aiming for enhanced capability on a general-purpose rifle. The focus is on reliability testing with common, low-power ammunition like PMC Bronze and Wolf Military Classic, using a specific AR-15 configuration (carbine gas, H2 buffer, chrome silicon spring). The speaker, a professional firearms instructor, emphasizes that failure to cycle such ammunition would render the rifle unsuitable as a training tool, highlighting practical, real-world application over theoretical performance.

The review details technical specifications, physical inspections including borescope analysis and gauging, and extensive range testing with 30-shot groups across multiple ammunition types. The data provides valuable insights into the barrel's real-world performance and accuracy potential.

This video compares carbine-length and mid-length gas systems on AR-15 platforms, using a Radian Model 1 as an example. Mid-length systems offer smoother shooting with less recoil and wear due to lower pressure and dwell time. Carbine-length systems provide greater reliability in adverse conditions by utilizing higher pressure to cycle the action, even when dirty.

The 12.5" AR-15 barrel, often dubbed the 'Bastard Sword,' presents a challenging compromise between size and performance. While it aims to offer 14.5" velocity in a shorter package, it often results in difficult gas system tuning, leading to overgassing when suppressed or undergassing unsuppressed. This length is also awkward for legal compliance, being too short for a standard rifle without muzzle device extensions and too long for typical SBR configurations.

This video from Brownells Gun Tech™ explains the concept of 'dwell time' in AR-15 firearms. It details how the duration that combustion gases act on the operating system is crucial for diagnosing cycling malfunctions and selecting the appropriate gas system for AR-15 builds. The video highlights that gas system length (Pistol, Carbine, Mid-Length, Rifle) is a primary indicator of dwell time, with shorter systems generally experiencing higher gas pressure due to the gas port being closer to the chamber.

This video provides an out-of-the-box review and "does it run" test of a Bear Creek Arsenal (BCA) Gen 2 Side Charger rifle chambered in 7.62x39mm.
