This Weihrauch HW77/97-PG4 FP/FAC 26 mm tuning kit by Vortek sets the power output of your Weihrauch HW77/97 to FP/FAC (24 Joules or 17 ft/lbs) values. It also increases the overall performance of your air rifle because of the high quality and perfect fit of the parts. The shooting characteristics of your rifle improve as well because of the decrease in twang (vibration) when you take a shot and the reduction of torsion and friction by the use of self-lubricating material.
