hey i have a problem..i had arms send me the fron screw that was missing and i just left the gunsmith to have it put on a scope installed. The front part that makes pressure is stripped or cross threaded and will not budge. He disassembled it to no avail. According to arms it was tested when it left there facility. Best they can do is sell me a new mount. The gunsmith said he can shim it and i will owe him on hour at $60 or i can send it back to you and hope you will give me a refund. How do you suppose we handle it. thanks again warren my number is 843 509 3479
