The M.O.A. trigger (Minute of Angle) is pre-set at the factory.  The trigger pull weight is pre-set at 3.5 to 4 pounds and can be adjusted within a range of 3 to 5 pounds.  Though trigger adjustments should be unnecessary, the trigger pull weight and overtravel can easily be tuned to your specifications.   We recommend this procedure be performed by a qualified gunsmith.
