The Tru Fire Hardcore 4 Revolution incorporates all the great features from the Hardcore 4 Finger with revolutionary new features. The 360 degree head rotation can now be locked into any of the 360 degree positions along the trigger. An 11 ball bearing system ensures smooth rotation of the head. The trigger knob can be located in 1 of 16 different positions along the trigger. Both the trigger and the tension can be adjusted independently with just the turn of a separate set screw and an adjustable lanyard bolts to the release so you can keep it with you at all times.
