Description
Maximise your air rifle’s performance with the CustomAirSeals Premium Tuning Kit for Weihrauch HW97 and HW77 air rifles.
Engineered specifically to eliminate the annoying spring “twang” and vibration common in factory setups, this drop-in upgrade significantly improves your firing cycle. Smoother cocking, reduced recoil, and more consistent velocities lead to tighter groups downrange.

🎯 Why Choose the 2-Piece Delrin Design?
Unlike rigid steel or single-piece guides that cause harsh metal-on-metal friction and buzzing, our 2-piece black Delrin system allows the guide components to rotate independently under heavy spring loads. This effectively absorbs harmonic vibrations and neutralises rotational torque. Delrin is incredibly wear-resistant, holds lubrication exceptionally well, and will not warp or degrade over time under heavy spring pressure.
