The Colt Infantry Automatic Rifle (IAR)

This video demonstrates a VTAC board drill focused on barricade shooting proficiency. The drill involves engaging targets from various positions (center, slant, side ports) using an AR-15 equipped with a Trijicon ACOG and RMR. The shooter, exhibiting experienced authority, successfully navigates the drill, highlighting effective recoil management and smooth transitions between shooting positions.

This guide details essential gear and techniques for Automatic Rifleman skills, as demonstrated by a Professional Tactical Firearms Instructor from Regular Guy Training LLC. It covers rifle setup, including the M556 A4 with a Cold Hammer Forged barrel and Surefire muzzle brake, emphasizing the importance of a Forced Reset Trigger (FRT) system. Key techniques include establishing Natural Point of Aim (NPA) for stable prone shooting, effective burst fire drills for terrain denial, and proper standing posture for recoil management during rapid fire. The instruction highlights practical field considerations like heat management, stock selection, and carrying spare parts.

This video argues that 9mm Pistol Caliber Carbines (PCCs) are a more practical and cost-effective training platform than 5.56 AR-15s for most civilians in the United States. The instructor emphasizes the superior availability and affordability of 9mm ammunition, which allows for more frequent and realistic training. While acknowledging the superior ballistics of 5.56, the video highlights that 9mm PCCs offer sufficient performance for common engagement distances and scenarios, especially in urban or vehicle environments. The instructor, identifying as an MMTC Marksmanship Master Trainer, stresses that skill is repetition-based and training with the platform you'll actually use is crucial.

This guide details tactical shooting techniques with the Brownells BRN-4, emphasizing its performance in both daytime and low-light conditions. The video showcases proficient recoil control, the effectiveness of the short-stroke gas piston system, and the rifle's utility with night vision equipment. Expert instruction highlights precision and positional shooting from prone and moving stances, demonstrating the BRN-4 as a capable tactical platform.

The Iraqveteran8888 "Meltdown" video series, while primarily for entertainment, offers educational insights into firearm durability under extreme stress. The videos demonstrate that AR-15 gas tubes are a common failure point, often exploding around 650-750 rounds of full-auto fire. This testing highlights the importance of materials like Inconel for components subjected to high heat and pressure, suggesting potential for improved firearm design and longevity.

This guide details a comparative performance drill for the Sig Sauer MCX Rattler LT across three calibers: 5.56 NATO, 7.62x39mm, and .300 Blackout. Conducted at Take Aim Training Range by Classic Firearms experts, the drill involves speed and accuracy tests, including a 5-round transition drill at 15 yards. The 5.56 variant demonstrated the least recoil and fastest return to zero, while all calibers showed distinct terminal ballistics in ballistic gel tests.

This guide traces the historical evolution of the AR-15 platform, from Eugene Stoner's initial M16 designs to modern iterations like the M4A1 Block II and MK18 Mod 1. It highlights key developments in barrel length, gas systems, and modularity driven by military requirements. The information is presented with an authoritative tone, demonstrating deep expertise in the platform's history and technical specifications.

This guide details the construction of the GTFO Marker, a concealed self-defense tool disguised as a Sharpie marker, as demonstrated by Wick from Shark Coast Tactical. The process involves modifying a standard Sharpie to house a sharpened carbon fiber rod, reinforced with epoxy for structural integrity. The final step ensures the marker retains its realistic appearance. This project requires moderate DIY skills and careful attention to detail to create an effective, discreet tool.

This video provides an expert look inside the Maxim 22 suppressor, demonstrating its disassembly and reassembly. The presenter, with high authority from Shark Coast Tactical, explains the physics of gas dissipation through the monolithic baffle core. The Sig Sauer P322 pistol is also showcased, highlighting its features and availability.

This video provides a silent, ASMR-style demonstration of mounting a SureFire SOCOM suppressor and an EOTech optics suite (EXPS3 with G33 magnifier) onto a Daniel Defense MK18 rifle. It showcases fluid weapon manipulation, proper suppressor attachment, and the functionality of the tactical optics. The presenter, identified as a professional firearm handler/retailer, highlights the tactile feedback of the rifle's controls.
