RISE Armament "Don't Tread on Me" RA-140 AR-15 Curved Super Sport Drop-in Trigger, Single Stage

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. The single-stage, 3.5-lb. Trigger is a significant upgrade over stock, giving you better control and precision.

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.

• Fits AR-style platforms built to mil-spec dimensions (calibers include .223/5.56, .308, 6.5, 9mm, and more)
• True drop-in installation, no gunsmithing required
• Non-adjustable 3.5-lb. trigger pull
• CNC machined from high-grade, heat-treated tool steel
