Tired of your AR-15's gritty, heavy stock trigger pull? Here's the easy, budget-friendly way to give your rifle the trigger it so richly deserves. The RA-140 SST features a self-contained design that makes it easy and quick to install with no fine-tuning needed—and no gunsmithing required. You'll find the single-stage, 3.5-pound pull to be a significant upgrade over stock.
PLEASE NOTE: KNS Anti-Rotate Pins recommended (but not required). KNS Anti-Rotate Pins prevent the trigger and hammer pins from "walking" loose while shooting. Additionally, the set screw should NOT be tampered with. Any attempt to modify the trigger will void the warranty.
