Rise Armament RA-140 Don't Tread on Me Flat Trigger 3.5lb AR-15

The Rise Armament RA-140FDTOM delivers precision trigger control with patriotic styling for AR-platform rifles. This single-stage flat trigger combines a crisp 3.5-pound pull weight with distinctive Don't Tread on Me flag finish engraving.

What Makes This Different

Unlike standard mil-spec triggers with their heavy, gritty pulls, the RA-140 features a precision-machined single-stage design that breaks cleanly at 3.5 pounds. The flat trigger face provides increased surface area for consistent finger placement, while the patriotic laser engraving adds visual appeal without compromising function. Rise Armament's manufacturing process ensures consistent pull weights within 0.25 pounds across all units.

Key Features

The RA-140's consistent break point enhances accuracy for competitive shooting and precision applications.
