Triggers

The trigger is where a rifle's mechanical accuracy either reaches the target or does not. A heavy, creeping trigger makes you move the rifle while breaking the shot, and no amount of good glass or a good barrel compensates. It is usually the single most noticeable upgrade on an AR-15.

Single-stage triggers break cleanly from a consistent weight and suit precision and competition. Two-stage triggers have a light take-up followed by a defined wall, which is what most people prefer for a general-purpose rifle because you can find the wall under stress without firing. Drop-in cassettes install in minutes; component sets cost less and require more care. Function-check carefully afterwards, every time.
