The Rock River Arms .156" 2-Stage Trigger is a drop-in, match-grade upgrade for AR-15 rifles that delivers a crisp, predictable pull for improved precision. Built from durable steel with a matte black finish, this National Match trigger kit uses a low-mass hammer and carefully tuned sear geometry to provide a smooth two-stage break in the 4.5–5 lb range.

This trigger is ideal for shooters who want more control and consistency from their AR platform, whether for competition, varmint hunting, or dedicated range use. Designed to fit AR-15 receivers that use .156" hammer and trigger pins, it installs easily and includes the necessary pins for a secure fit. The refined pull and shortened lock time help you call every shot with confidence, backed by Rock River Arms’ reputation for reliable, well-crafted AR components.
