Reflex red dot ring holder
A simple tool to hold the ring of a reflex red dot to help screw/unscrew from the top. The sight could be used for airsoft, and for real I suppose.
Fit perfectly on mine. I hope it will be the same for you.
Feel free to remix it if necessary, specially if you want to create an all-in-one tool that hold the ring and screw too (it was the original idea...)
