This guide addresses compatibility issues between the Radian Talon 45/90 Safety selector and various aftermarket AR-15 triggers, particularly in the 45-degree short-throw setting. It outlines troubleshooting steps, lists known incompatible triggers, and explains the underlying cause of 'tolerance stacking.' The information is presented critically, highlighting a lack of transparency from manufacturers regarding these technical limitations.

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 review of the Andro Corp ACI-15 budget AR-15 highlights its performance over 1,000 rounds. While it offers good value with features like an M-LOK rail and ambi safety at its price point, the rifle exhibited significant reliability issues when dirty, specifically failures to feed and excessive brass ejection. Thorough cleaning and lubrication improved performance, but the rifle was deemed not a good 'dirty shooter' and placed at the bottom of the sub-$500 AR-15 tier list by the reviewers.

This guide details common issues encountered with budget AR-15 platforms, focusing on potential malfunctions and their causes. It covers gas port size and alignment, feed ramp issues, magazine catch installation, safety selector spring failures, broken forward assist assemblies, leaking gas keys, worn gas rings, and improperly machined bolt lugs. The information is presented from personal experience to help owners troubleshoot their firearms.

This video from School of the American Rifle highlights the importance of a functioning ejector on an AR-15 bolt. It demonstrates how a seized ejector can cause a firearm to stop working. The instructor explains that dual ejector bolts offer a redundancy, as one ejector can fail and the other can still ensure proper ejection.

This video from School of the American Rifle demonstrates a potential issue with some Radian selectors where they can jump out of timing. The instructor shows how applying specific pressure can cause the selector to become stuck, preventing it from engaging fire. While not indicative of a universally bad product, it highlights a potential failure point that users should be aware of and know how to correct.

This video details troubleshooting a Noveske N4 Switchblock that experienced significant malfunctions, including light strikes, extraction failures, and ejector issues, after approximately 800 rounds. The presenter found the Switchblock to be finicky with buffer systems and explored swapping components, including a Centurion bolt carrier. After returning to factory parts and cleaning, the rifle appeared to function correctly, though the exact cause of the initial problems remains somewhat unclear, potentially related to gas rings or component tolerances.

This video demonstrates the installation and function of the Brownells Offset Buffer Retainer. It addresses common AR-15 issues where the buffer may be too far forward, impacting the buffer retainer during assembled operation. The offset retainer provides a solution for improperly drilled lower receivers, overly long barrel nut threads, or short bolt carrier groups.

This guide details a comprehensive physical inspection and testing procedure for a Toolcraft Nickel Boron Bolt Carrier Group (BCG). It covers checking gas ring integrity, carrier bore measurements, gas key staking, borescope inspection of internal finishes, bolt component checks, firing pin protrusion, and headspace. The process highlights potential issues like excessive wear, uneven coating application, and critical dimensional tolerances that can affect firearm reliability.

This video demonstrates four distinct methods for measuring and checking the firing pin protrusion on an AR-15 platform rifle. Understanding correct firing pin protrusion is crucial for reliable ignition and safe firearm operation. The content focuses on practical gunsmithing techniques applicable to AR-15 owners and maintainers.

This video delves into the common AR-15 buffer rattle phenomenon. It aims to explain the underlying causes by examining the buffer's construction and design. The creator, Deuce and Guns, plans to release new content weekly and encourages viewers to like and subscribe.
