Good idea but no confidence - B-Square Shotgun Universal Cantilever Mounts - Ribs up to 3/8", Blue 16175

I bought it hoping I can use my shotgun with a red dot for deer or turkey a well but the design is not optimal and not easy to set up.
I am not even sure it will remain in position. That was a wrong decision.
Writing longer to help with this stupid rule of having 200 characters minimum in a review ... Not sure I will spend this time again ...
