The new CNC speed trigger features an innovative Delrin bearing that delivers an incredibly smooth pull and optional adjustments for pre-travel, post-travel and actuation.Built on the MTW-Spec, the Article I is compatible with a countless number of MTW-Spec and real-steel aftermarket components, giving it limitless customizability.FeaturesSkeletonized MTW-Spec CNC Billet Aluminum Receiver set with CNC Feed TubeGenuine Carbon Fiber Outer Barrel with 150mm inner barrelBlacked out INFERNO Gen 2 with Heretic Labs programming and binary fire modePTS EPM-MTW mag with empty mag detectionCNC Speed trigger with low friction bearing and travel adjustmentPicatinny Stock Adapter with QD pointSpecsWeight: 2.1 lbs (.95kg)Input Pressure: 60-140 psiEstimated Energy Range: 0.8 1.65 JROF: 5-35 RPS adjustableBattery input: JST 6-8V
