Overview
The Geissele Automatics G2S Two Stage Trigger is designed specifically for the AR-15 platform, providing a distinct two-stage pull that enhances precision during shooting. The first stage allows for a smooth take-up, while the second stage provides a crisp break, making it ideal for both accuracy and control in rapid fire scenarios. This trigger is commonly found in builds utilizing a carbine gas system and chambered in 5.56 NATO, making it a favored choice for those looking to optimize their AR-15 performance.
