Rise Armament RA-100F Two-Stage Flat Drop-In Trigger AR-15/AR-10 - 4.5 lb

The Rise Armament RA-100F is the flat-faced variant of Rise Armament's workhorse RA-100 two-stage drop-in trigger, purpose-built as a rugged upgrade for AR-15 and AR-10 platforms fitted with standard small-pin mil-spec trigger groups. The trigger is machined from steel and finished in a durable black nitride coating for long wear life and corrosion resistance. It ships ready to install right out of the box with the springs already mounted and the required mil-spec pins included.

The RA-100F uses a smooth two-stage pull with a light 1.5 lb first stage that transitions into a crisp 3 lb second stage for a total pull weight of 4.5 lb. The flat blade provides a consistent finger placement for repeatable trigger control, and the design is tuned to outperform mil-spec with smoother operation, a cleaner break, and stronger performance. Whether you run a duty carbine, a precision AR-10, or a hard-use general-purpose rifle, the RA-100F is a true workhorse trigger ready to handle tough conditions shot after shot.
