Hi,For anyone interested for a scope mount that dampens all the recoil and the surge of his powerfulspringer or any other FAC airgun, I have just released the 3d printing plans on Thingiverse togetherwith a short Youtube instructions video.It works much better than other similar mount and it has been measured with a 400G accelerometer setup.It reduces the acceleration to less than 125 G while all other designs go over range consistently.I still cannot post any links in the forum, so you can find the video be searching on google the following:"Zero Recoil Zero Play scope mount - 3d plans" (with the quotation marks)Have fun!
