"Necessity is the plea for every infringement of human liberty. It is the argument of tyrants; the creed of slaves."-William Pitt the Younger
Unfortunately, the Valdada mounts don't use helicoils. (Have already stripped one hole on my 2-12x.) How do you like the 3-18x?
“Americans have the right and advantage of being armed – unlike the citizens of other countries whose governments are afraid to trust the people with arms.” -- James Madison
ADM is the cat's back, I think there the best mount on the planet. It is all that I use anymore and have yet to have a single problem. The one time I called to buy some new hex head bolts for a used mount I bought that the previous owner had lost, they insisted on sending me a new set for free. ADM is good people!
