Description
The Rise Armament RA-140 Super Sporting trigger is a high-performing, cost-effective drop-in upgrade designed to replace mil-spec triggers in AR-platform rifles. Part of Rise Armament’s popular RAVE 140 lineup, the RA-140 (also referred to as the SST – Super Sporting Trigger) is built to deliver a clean, crisp break for sport, competition, and recreational shooting applications.
This version features a straight, flat trigger blade preferred by many shooters for a consistent, linear pull. The single-stage design delivers a clean break with a 3.5 lbs draw weight, providing a noticeably lighter and crisper feel over standard mil-spec triggers. The trigger is CNC machined from high-grade, heat-treated tool steel and aluminum components, then finished in a durable black hardcoat anodized coating to withstand harsh environments and the recoil of powerful AR-platform cartridges.
The RA-140 installs as a drop-in unit in right-hand AR-15 and AR-10 pattern lower receivers, and includes anti-walk trigger pins for a secure, hassle-free installation. Made in the USA and backed by a lifetime warranty, the RA-140 Flat Super Sporting Trigger is a proven, budget-friendly upgrade that transforms the feel of any compatible AR-platform rifle.
