Monotheist, Your King looks great! I am in the middle of my own RC Armory KT. I was going to go with a coil actuated/ spring return recoil till I saw your excellent recoil action. Any chance of seeing a picture of the recoil unit from the other side? And are you using any type of bearing for the barrel to slid in? I have been looking into using a linear bearing on mine. Again, your King looks great! Paul
