Rise Armament RA-140 Don't Tread on Me Single-Stage Flat Trigger 3.50 lb - DTOM Flag Finish

The Rise Armament RA-140 Don't Tread on Me is a drop-in single-stage flat trigger built for the AR-15 and AR-10 platform. Carrying a clean 3.50 lb draw weight, this edition of the popular RA-140 Super Sporting trigger delivers the same crisp, competition-style break and short reset the line is known for, with a flat trigger shoe that lets the shooter's finger track straight back through its natural arc for cleaner trigger control, less disturbance to the rifle as the shot breaks, and faster follow-up shots.

True to the rest of Rise Armament's single-stage drop-in triggers, the RA-140 features no take-up, a telltale short reset, and is fully self-contained in an easy-to-install housing precision-machined from 6061 aerospace aluminum with internal components of steel. The unit drops into a standard AR lower with no permanent modification required, making it a straightforward upgrade for precision builds, competition rifles, and duty-oriented carbines alike.

What sets this version apart is the Don't Tread on Me Flag Finish, with the iconic DTOM rattlesnake flag graphic laid into the aluminum housing. It is a distinct cosmetic variant of the standard RA-140, offering the same drop-in performance and reliability in a finish tailored for shooters who want their trigger to match a patriotic build theme.
