For an ultra-crisp single stage trigger press with a glass-smooth break and no grittiness or creep prior to hammer release, you need a CMC Yella Jacket AK2.0 Elite Single Stage Drop-In 3.5 lbs trigger. CMC's proprietary machining process renders a superior surface finish of 1-2 RMS as opposed to electronic discharge machining which leaves a 32 RMA finish. A mirror has a RMS of zero for comparison.Even with a factory set trigger pull weight of 3.5 lbs the reset is positive and allows for quick follow-up shots. Installation of the self-contained one-piece trigger is easy. Every CMC Drop-In Trigger is hand assembled and hand tested for reliability. When AK shooters demanded a light, fast, and smooth trigger CMC answered the call with the Single Stage 3.5 lbs Trigger.The innovative design of the Combat Curved Trigger combines the comfort of the classic curve with CMC's signature flat trigger indexing into one dynamic trigger bow for the modern warfighter. The CMC CCT has an exceptionally smooth feel, ultra-clean break, and an exceptional lock time and lightning-fast reset.Features: Single Stage Drop-In Yella Jacket Combat Curved Trigger Factory Set 3.5 lbs Trigger Pull Ultra-Crisp, Glass-smooth Break Positive Trigger Reset Self-Contained One-Piece Assembly 8620 Alloy Steel, S7 Tool Steel and 7075-T6 Aluminum Construction Easy to Install Made in the Great State of TexasSpecifications: Activity: Shooting Color: Yellow/Black Firearm Fit: AK-47 Product Type: Triggers Trigger Pull: 3.5lbs Trigger Type: Single Stage
