I just finished building an amd-65. I was going to test fire it before parkerizing and was told it is very important to check the headspace before test firing. Does anybody have a set of gauges they're willing to check my rifle with or let me borrow them? I'll pay you to if you'ld like. Does anybody know of a way to do this without gauges? I'm in the gresham area and would appreciate any help or input you have. Thanks
