Duration: 13:41

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.

Quick Summary

The Radian Talon 45/90 Safety can experience compatibility issues with certain AR-15 triggers, especially in the 45-degree short-throw mode. This is often due to 'tolerance stacking,' where minor manufacturing variations prevent proper function. Switching to the 90-degree setting usually resolves the problem, but transparency from manufacturers regarding these limitations has been criticized.

Frequently Asked Questions

What are the main compatibility issues with the Radian Talon 45/90 Safety?

The primary issue arises when using the Radian Talon safety in its 45-degree short-throw setting with certain aftermarket AR-15 triggers. This can lead to the safety selector not engaging or disengaging properly due to manufacturing tolerance stacking.

Which AR-15 triggers are known to have issues with the Radian Talon 45/90 Safety?

Known problematic triggers include specific models from Geissele Automatics (SSA, SSA-E, G2S, SD-C), Elf Tactical, Wilson Combat, CMC Triggers, and Rise Armament, particularly when the Talon safety is set to the 45-degree throw.

What causes the incompatibility between the Radian Talon safety and certain triggers?

The incompatibility is largely attributed to 'tolerance stacking.' Minor variations in the manufacturing tolerances of both the safety selector and the trigger mechanism can prevent them from interacting correctly in the 45-degree configuration.

What solutions are available for Radian Talon safety and trigger compatibility problems?

The most common immediate solution is to switch the Radian Talon safety to the 90-degree setting. If this doesn't resolve the issue or a 45-degree throw is desired, exploring alternative safety selectors or triggers known for broader compatibility may be necessary.
