Description
This bundle pairs two high-impact upgrades for AR-15 builders who want cleaner trigger control and faster, more confident manipulation at the receiver. The Dirty Bird Single Stage Quick Reset Drop-In Trigger (Flat) delivers a crisp 3.5 lb pull with minimal take-up and a strong, tactile reset, all in a self-contained cassette that installs easily and includes anti-walk pins. Paired with it is the Atrius Development 3 Position Super Selector Safety, a robust SAFE / SEMI / SUPER-SEMI selector with positive detents and a crisp 90° throw, built from heat-treated steel for hard-use durability.
This kit is a great fit for serious range rifles and duty-minded builds where consistent trigger feel and positive selector engagement matter most.
