Be American, Build an AR

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 details the evolution of AR-15 carrier key staking from early 'Gen 1' square staking to modern 'Gen 5' OCKS with serrated heads. It emphasizes proper torque values (vintage 35-40 in-lbs, modern 55-58 in-lbs) and the importance of sufficient metal displacement for screw security. The video, presented by an expert from School of the American Rifle, critiques commercial staking and references historical technical manuals.

This video, titled 'Bore Buddy - Not Full Auto FRT', appears to be a discussion or demonstration related to firearm components, specifically the 'Bore Buddy' and its connection or lack thereof to 'Full Auto FRT' (likely referring to a Full Auto sear or trigger mechanism). Given the title's focus on a specific component and its function, the content is likely technical in nature, potentially exploring modifications, functionality, or limitations of this firearm part. The absence of a transcript requires an assumption that the video delves into the operational aspects of the Bore Buddy.

This YouTube video appears to explore modifications or accessories that allow a pistol to be used in a manner or configuration resembling an AR-15 platform. The title suggests a transformation or adaptation of a handgun to incorporate features or functionalities typically associated with AR-15 rifles. The content likely focuses on specific products, custom builds, or conversion kits designed to achieve this hybrid functionality, potentially covering aspects like improved ergonomics, stability, or sighting systems. The video aims to demonstrate how a pistol can be made to feel or perform more like a rifle.

This guide details how to repurpose a worn AR-15 receiver set into a dedicated .22 LR build, a project undertaken by Hop due to excessive assembly and disassembly. The video highlights the advantages of dedicated .22 LR barrels over conversion kits and showcases specific components like a CMMG barrel and bolt kit, a Ballistic Advantage rail, and a Catch22 bolt catch for enhanced functionality. It also touches on suppressor performance differences for rimfire applications.

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 Walther PPK/S review highlights its return to the market, featuring a hybrid American frame and German slide to bypass import restrictions. The .380 ACP pistol boasts a classic design with integrated sights, a DA/SA trigger, and a slide-mounted safety/decocker. It includes two magazines, one with a finger rest, and a unique extended beavertail to prevent slide bite.

This AR-15 build, featuring high-end components like F1 Firearms receivers and a POF Dictator adjustable gas block, suffers from short-stroking malfunctions. Despite an open gas block and lightweight parts, it fails to cycle reliably. The speaker investigates potential issues with the buffer system and carrier group, highlighting the complexity of tuning lightweight AR builds.

The Bersa TPR9C is a modern 9mm evolution of the classic Thunder series, offering a compact design suitable for concealed carry and self-defense. It features a smooth DA/SA trigger with a short reset, ambidextrous controls, and a tactical ledge sight for one-handed racking. The firearm demonstrates good ergonomics and full case support in the chamber.

This review covers the Smith & Wesson Performance Center Pro Series Compact 1911 in 9mm, highlighting its 8+1 capacity, bull barrel, and scandium frame. The firearm features a slim profile, ambidextrous safety, and a rounded butt for concealed carry. While the trigger is noted as suitable for carry, caution is advised with reloads due to a partially unsupported chamber.
