Reapers Airsoft was given the Precision Run Hop-Up Bucking made by the Airsoft Philospher to review... "Hello the ladies ;-) About three weeks ago Marvin or Airsoftphilosopher visited me and left me one of his precision runs incl. Buckings for testing. In this video we will talk through the running / bucking combination and look at the results at 60 ° and 40 °. Unfortunately, the current temperatures are not exactly helpful for such a test, but I think you can still see how the system works."
