Hey guys,i made a review about the TBT Tuning Kit for Weihrauch HW30S and Beeman R7. I tested this kit for about two month and many hundreds of shots. These Kits are also available for many other Weihrauch and AirArms Airgun Rifles! https://www.youtube.com/watch?v=DD-XRCFCQXA Have fun watching and don´t forget to subscribe my channel ;-) Best regardsAirGhandi
