This video provides an in-depth review and ballistic testing of the Centurion Arms FBI 11.5-inch CHF barrel. The presenter details its construction, technical specifications, and performance with various ammunition types, offering group sizes, velocities, and comparisons to other barrels. The review highlights the barrel's potential for accuracy despite minor cosmetic imperfections.

This guide details essential pre-purchase and pre-firing checks for AR-15 platforms, focusing on assembly quality rather than material cost. It covers critical areas like barrel extension alignment, headspace, gas block installation, BCG integrity, and lower receiver fit. Performing these checks can prevent malfunctions, ensure reliability, and save money on potential repairs, especially with more affordable AR-15 models.

This guide provides a quick external assessment of an AR-15 for potential buyers, focusing on common issues that indicate builder inexperience or potential problems. Key checks include magazine catch alignment, castle nut security, buffer tube orientation, gas tube installation, and muzzle device tightness. The assessment is designed to be performed without disassembling the firearm, making it suitable for gun shows or shop environments.

This guide provides nine essential tips for building an AR-15, presented by CJ from AT3 Tactical. It covers crucial steps like dry-fitting components, proper roll pin installation, gas block alignment using the spaghetti method, managing small parts with Ziploc bags, adhering to torque specifications, smart lubrication techniques, trigger installation, using a soft-faced hammer, and maintaining a clean workspace. The advice aims to make the AR building process smoother and faster.

This video debunks common AR-15 building myths, focusing on the necessity of specialized tools and techniques. It clarifies that standard upper receiver blocks are sufficient for most builds when using reasonable torque specs for the barrel nut. The presenters also explain that gas block alignment is more forgiving than often believed due to the gas port's size and that clamping the barrel during muzzle device installation is acceptable. Finally, they address the misconception that using a torque wrench to loosen fasteners damages it, explaining its internal mechanics.

This guide details the installation of the Samson SXT handguard on an AR-15 platform. It covers the disassembly of existing components, preparation of the barrel and receiver with lubricant, proper torque specifications for the barrel nut and handguard screws, and alignment of the gas block and tube. The video highlights unique features like the gas tube support and steel QD inserts.

This guide details common AR-15/AR-10 build mistakes and their solutions, as explained by Steve and Caleb from Brownells. Key areas covered include preventing accessory screw interference with the gas block, ensuring proper gas block alignment, adhering to the 40 ft-lbs torque spec for castle nuts, avoiding over-lapping upper receivers during lapping, and correct buffer tube installation depth. Following these steps ensures reliable function and accuracy.

This video details the challenges and common mistakes encountered during an AR-15 build competition. It highlights critical steps like proper gas tube and buffer tube installation, gas block alignment, and optic mounting. The builders faced issues such as upside-down gas tubes, misaligned gas blocks, incorrect buffer/spring combinations, and loose optic mounts, leading to malfunctions during testing. The competition emphasizes the importance of attention to detail and focus under time pressure.

This video details troubleshooting and testing of two custom-built firearms: a 7.62x39 pistol and a .308 AR-10. The presenter, Elliott Delp, addresses previous cycling issues by adjusting the gas block alignment on the 7.62x39 pistol and modifying the buffer system. The .308 build also faced cycling problems, with potential causes like a mis-milled charging handle and buffer weight being investigated. The testing reveals partial success with the 7.62x39 pistol using Tula hollow points, but subsequent attempts with Red Army FMJ ammunition encountered feeding and cycling failures.

This live Q&A session covers a wide range of firearms topics, including magazine recommendations, rifle component compatibility, historical firearms analysis, and ammunition availability. The host, a firearms instructor, discusses specific models like the Duramag, LWRC rifles, FN's production of M16s/M4s, and the Beretta ARX. He also addresses common concerns such as AK vs. AR reliability, the impact of barrel length on ballistics, and the current ammunition shortage.

This guide, presented by Caleb from Brownells, addresses the top three causes of AR-15 malfunctions, focusing on issues common among home builders. It details how improper gas block alignment, incorrect buffer weight/spring combinations, and backward hammer spring installation can lead to feeding, extraction, ejection, and light strike problems. The instruction emphasizes understanding the root causes to effectively troubleshoot and maintain the AR-15 platform.

This video demonstrates the use of 223 Innovations' Gas Block Genie and Roll Pin Wizard tools for AR-15 assembly. The Gas Block Genie ensures precise gas block alignment by marking the barrel, preventing potential cycling issues. The Roll Pin Wizard simplifies the installation of roll pins and the pivot pin detent/spring assembly, mitigating common frustrations and damage during lower receiver assembly.
