VULCAN OWNER'S MANUAL. Trigger adjustment Main
Trigger pull adjustments can be achieved by varying the tension on the trigger adjusting spring .The range of adjustment is approximately 3 to 5 lbs (1.36 to 2.27 kg).The adjusting screw is located on the top of the body end plug and is flush at the lowest setting. The corresponding movement of the screw is 1/4" (6.35 MM).
Using the Allen key provided, turn clockwise to increase the trigger pull and anticlockwise to lighten the trigger pull. Do not unscrew above the top of the body end plug, otherwise contact with the spring will be lost. Conversely, do not over-tighten, causing the spring to be compressed solid and thus preventing movement of the trigger.
Always remember to check that the safe is disengaged when checking the trigger pull and to point the rifle towards the ground, even without a pellet in the barrel.
