Caleb from Brownells provides a detailed installation guide for the Geissele Mk18 handguard on an AR-15 platform. The video covers the necessary tools, preparation steps, barrel nut torquing, gas system installation, and final handguard mounting. It emphasizes proper torque specifications and alignment for a rigid and precise build, highlighting the handguard's suitability for precision AR-15 builds.

This video provides a comprehensive guide to upgrading a Smith & Wesson M&P10 rifle. It details the step-by-step process of replacing the stock, grip, trigger, buffer tube assembly, handguard, gas block, and muzzle device. The instructor also covers the installation of accessories like a bipod, charging handle, and iron sights, demonstrating advanced gunsmithing techniques for a large-frame AR platform.

This video delves into the specific engineering behind a firearm's pinpoint accuracy, focusing on barrel specifications and gas block design. It highlights the critical role of a 1:5 twist rate in a stainless steel barrel for optimal performance and discusses a proprietary jam nut style gas block system that simplifies installation and ensures precise alignment.

This guide explains the benefits and installation of free-float handguards for AR-15 platforms, emphasizing their role in improving accuracy and modularity. It details different types like quad rail, MLOK, and carbon fiber, and provides a decision matrix for selecting the right handguard based on build objectives and budget. The video also covers common mistakes, maintenance, and debunks myths surrounding free-float systems.

This video demonstrates the use of the Brownells BRN4/HK416 Bench Block, a specialized tool designed for AR builders. It facilitates the installation and removal of gas block pins on BRN4 and HK416 pattern rifles, including those with M277/M38 profile barrels. The non-marring polymer construction and integrated punch holders make it a valuable tool for preventing damage during the build process.

This video introduces a new line of Brownells AR tools, including upper and lower receiver vice blocks, and a bench block. These tools are designed to aid in the assembly and maintenance of AR-15 and AR-308 platforms. Specific applications highlighted include barrel installation, gas block and bayonet lug roll pin work, buffer tube alignment, and castle nut staking, emphasizing secure component handling.

This guide details the process of building an M38-style rifle using a Brownells BRN-4 upper receiver. It covers the installation of an M27 profile barrel, an 11-inch quad rail handguard, and an HK-style gas block. The build also includes mounting a Leupold Mark 5 HD optic and the piston system, emphasizing proper torque specifications and alignment for a functional rifle.

This video provides a comprehensive overview of AR-15 gas blocks, explaining their critical role in the direct impingement system. It details standard block types, attachment methods (set screw vs. clamp-on), barrel diameter considerations (0.625", 0.75", 0.93"), and the importance of proper fit to avoid rail interference. The guide also covers adjustable gas blocks for tuning recoil and suppressor performance, while cautioning they add potential failure points.

This video details the process of assembling a MK 12 MOD 1 clone upper receiver. It covers the installation of a Douglas SPR barrel from Compass Lake Engineering, the Allen Engineering A5 suppressor system, and the KNS Armament RAS quad rail. The presenter emphasizes proper torque specifications for the barrel nut and alignment for the gas block and suppressor collar, offering insights into sourcing specific components for an accurate clone build.

This video demonstrates a common issue encountered during gas block installation: shallow or improperly tapped threads on the set screw holes. The instructor from School of the American Rifle shows how to identify this problem, where the set screw doesn't fully seat, leading to a false torque reading. A practical solution involving running a tap through the holes to clean and deepen the threads is presented as a quick fix, emphasizing that this is a common gunsmithing task rather than a reason to return a part.

This guide details a method for installing low-profile AR-15 gas blocks using a thumb screw for initial alignment and a borescope for precise gas port alignment. It emphasizes the importance of set screws with teeth for better grip and provides torque recommendations for thread lockers like Rocksett and high-temperature red Loctite.

This guide details the installation of the Palmetto State Armory Hex Rail on an AR-15 platform. It covers the proper torque specifications for the barrel nut (50 ft-lbs), gas block screws (30 in-lbs), handguard screws (40 in-lbs), and set screws (10 in-lbs). The process emphasizes careful alignment and sequential tightening of fasteners to ensure a secure and reliable handguard installation.
