Videos tagged with Geissele SD-C

This video exposes critical compatibility issues between the Radian Talon 45/90 Safety and several popular AR-15 aftermarket triggers, particularly in the 45-degree short-throw setting. The speaker, demonstrating high technical authority, details how 'tolerance stacking' can cause malfunctions, with specific interference points identified on Geissele triggers. Both Radian and Geissele acknowledge the problem, suggesting the 90-degree setting or alternative safeties as solutions, but the speaker criticizes the lack of upfront consumer warnings.

This video provides a direct comparison between the Geissele SD-C ($200) and AT3 Tactical Nickel Boron 2-Stage ($90) triggers. The demonstration uses a cutaway AR-15 lower receiver and a digital trigger pull gauge to objectively show the installation, mechanism, and measured pull weights. The Geissele SD-C tested at 3 lbs 0.0 oz, while the AT3 Tactical trigger measured 4 lbs 11.6 oz. The expert instruction highlights the importance of empirical data in selecting firearm components.
