This guide details the field stripping process for the Italian TZ-45 SMG, as demonstrated by an experienced instructor. It covers the removal of key components like the front sling swivel and muzzle nut to access the barrel and receiver. The function of the charging handle as both an operational part and a dust cover is also explained.

This video provides an expert-level breakdown of two custom AR-style rifle builds: one in 6mm ARC and another in 8.6 Blackout. The presenter, Justin from Cerebral Firearms, details specific components from manufacturers like Faxon Firearms, Griffin Armament, and Ranier Arms, offering insights into build choices and potential upgrades. He also touches on the use of the ACE Virtual Shooting Trainer and discusses the implications of upcoming gun legislation in Virginia.

This guide details a specific trick for disassembling the Smith & Wesson M&P9 (1.0 model) for cleaning. It highlights a common point of confusion where standard field stripping methods fail on this older version. The key is using a tool to manipulate an internal lever after locking the slide back, a detail often overlooked but crucial for successful disassembly. Instruction comes from an experienced source demonstrating clear expertise in M&P platform nuances.

This guide outlines the conceptual assembly of the unique XR-86 custom rifle, a project by Wilfred Ellis. It details the integration of parts from an M60, M14, and AR-15, highlighting the custom gunsmithing required to combine these disparate systems into a functional firearm. The process involves careful mating of bolt, gas, and trigger mechanisms.

This guide details the installation and integration of high-end components for a custom AR-15 build, as demonstrated by Tactical Advisor. It covers mounting the PWS MK111 MOD 2-M base rifle, optics like the Vortex AMG with a Midwest Industries mount, and specialized accessories including the Nitehog thermal, Holosun IRIS, and PWS suppressor. The process emphasizes proper accessory placement, cable management, and ergonomic considerations like grip orientation for an advanced builder.

This expert guide from the School of the American Rifle details how to identify and address rough carrier key bores in AR-15 bolt carrier groups. The instructor, demonstrating expert knowledge, explains how these manufacturing defects, particularly on Colt components, can lead to premature wear on the gas tube and reduced reliability. Solutions involve replacing the defective carrier key to ensure smooth operation and longevity of the firearm.

This guide provides expert instruction from nsz85 on how to properly load a 75-round drum magazine for the AK-47 rifle. It covers identifying components, resetting the follower, the specific loading procedure for rounds, winding the spring for tension, and crucial advice on releasing tension for storage to preserve spring life. The video emphasizes clear, step-by-step technical guidance for reliable firearm operation.

This guide details the process of installing a standard A2 style flash hider onto an AR-15 platform, specifically a 10.5-inch Rainier Arms barrel. It covers necessary tools, thread preparation with AeroShell 33MS grease, crush washer orientation, and the critical step of indexing the muzzle device for optimal performance, especially when shooting prone. The instruction emphasizes precise alignment with the gas port for proper function.

This guide details the critical process of checking headspace on an AR-15 build, a vital step for ensuring firearm safety and reliability. Professional gunsmith Dale Heckstrom from Little Crow Gunworks demonstrates the disassembly of the bolt carrier group, the precise use of 'Go' and 'No-Go' gauges, and the reassembly process. Proper headspace ensures the firearm operates within safe mechanical tolerances, preventing potential malfunctions or dangerous failures due to factory defects or mismatched components.

This guide, drawing from an expert assessment by nsz85, details the critical role of AR-15 buffers in rifle function. It covers buffer weight selection based on the principle of using the heaviest buffer that ensures bolt lock-back on an empty magazine. Key concepts like dwell time, overgassing, and their impact on extraction are explained, along with the mechanical differences between standard rattling buffers and those using tungsten powder.
