What If You DONT Clean Your AR? #civtac #pewpew #guns

This video demonstrates the assembly of an AR-15 lower receiver, focusing on the installation of critical components like the trigger group, safety selector, and buffer system. The builder, exhibiting advanced armorer skills, utilizes specialized tools and techniques for a precise build. While edited for entertainment, the process highlights the methodical approach required for a reliable firearm.

This guide addresses the common issue of gas blowback experienced when shooting suppressed AR-15 platforms, particularly the MK18. It details solutions ranging from personal protective equipment like Magnalens to mechanical adjustments such as installing an adjustable gas block or a PRI Gas Buster charging handle. The speaker, identified as FrenchGunGuy, emphasizes that these modifications not only improve shooter comfort by reducing gas in the face but also help correct over-gassed ejection patterns. For those interested in learning more about rifle tuning and gunsmithing, the Sonoran Desert Institute (SDI) is recommended.

This entry details the unique XR-86 custom rifle, a 1986 build by Wilfred Ellis. It masterfully combines components from an M60 (flash hider), an M14 (gas system), and an AR-15 (trigger, bolt, locking system). The AR-15 trigger is notably rotated 90 degrees, and its bolt is integrated with the M14 gas system, showcasing advanced gunsmithing.

This guide details the installation of an aftermarket AR-15 trigger, specifically a Timney Triggers product. The process involves unboxing the trigger, identifying its modular components like interchangeable shoes, and then carefully installing it into a lower receiver. A function test is crucial to confirm correct operation. The speaker demonstrates proficiency with firearm components and installation procedures.

This video from School of the American Rifle highlights critical manufacturing defects in AR-15 bolt carrier keys, specifically focusing on rough internal bores. Lead instructor demonstrates how a poorly finished carrier key can cause significant friction, premature wear on components like gas tubes, and operational issues, contrasting a problematic new Colt carrier with a well-functioning older model. The expert emphasizes the importance of a smooth bore for reliable function and longevity of expensive parts.

This guide, presented by an expert firearms instructor, details the benefits and installation of adjustable triggers for platforms like the AR-15. It covers understanding trigger mechanics, adjusting pull weight, reset, and overtravel, and highlights ideal users for these components. The instruction emphasizes safety and practical application for competition and precision shooting.

This comedic skit humorously emphasizes the critical importance of wearing eye protection at the shooting range. It illustrates a handgun malfunction, specifically a stovepipe, and uses a visual gag with a spent casing to drive home the safety message. The creator showcases tactical gear and a Sig Sauer P365 XL, demonstrating firearm handling in a range environment.

This video tests the penetration capabilities of various calibers, from .22 LR to .50 BMG, against a tree. Surprisingly, even the powerful .50 BMG round failed to penetrate the tree completely, demonstrating the significant stopping power of natural barriers against firearms.

This video explores the hypothetical concept of using a human body as a suppressor, simulating the scenario with ballistic gel. A Derya Arms .22 rifle is fired into a ballistic gel head, with the host noting the shot sounded 'dead silent'. The experiment demonstrates the penetration depth of a .22 LR round through the simulated head.

This test evaluates the ballistic protection of a Belgian M1 steel helmet against various calibers. While it stopped birdshot, .22, and .380 Auto rounds, it failed to defeat 9mm and .223 Remington rounds, indicating it is not suitable for protection against common handgun or rifle threats.
