Heretic Labs proposes the ultimate HPA Speedsoft instrument. In Article I, only that which is necessary for performance is included, shedding the weight of Milsim orthodoxy. It starts with a rugged but skeletonized MTW CNC billet aluminum receiver. Gone are the charging handle, buffer tube, and stock. In place of a rail, the genuine carbon fiber outer barrel keeps the front end light with a total pistol weight of 2.1lb.
 
 
The Article I is powered by the proven and reliable INFERNO Gen 2 HPA engine, coupled with an upgraded control board with a new binary trigger option. 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 countless MTW-Spec and real-steel aftermarket components, giving it limitless customizability.
