Overview
Single Stage | Flat Bow | 3.50 lb | Steel | AR-15 / AR-10 The CMC Triggers Exclusive Black Trigger is a pre-assembled, drop-in trigger unit for AR-platform rifles. It features a single-stage action with a factory-set 3.5 lb pull weight and a flat trigger bow. The trigger housing is constructed from steel. GPP build data shows this trigger commonly appearing alongside Aero Precision lower and upper receivers, often configured with a carbine-length gas system and chambered in 5.56 NATO. It's also often paired with the B5 Systems Type 23 P-Grip.
Pros
