Overview
The PSA Custom AR Single-Stage Drop-In Trigger with a curved bow is designed for AR-15 platforms, providing a straightforward and consistent trigger pull without the need for additional adjustments. As a single-stage trigger, it offers a direct connection from the trigger pull to the sear release, resulting in a clean and responsive break that many builders appreciate for improved accuracy and control. This trigger is commonly found in builds featuring a mid-length gas system and chambered in 5.56 NATO, making it a solid choice for those seeking reliability and performance.
