I've got a NM M1A and recently purchased a SADLAK scope mount. I've mounted it 8 times now and either the rear is not sitting solid or there is no elevation available once the scope is mounted. I have all the instructions for measuring out of spec receivers but don't have the tools needed. Does anyone know of a reliable gunsmith near Houston that can reliably set up the SADLAK scope mount so I still have decent elevation? I searched but nothiong about haveing the SADLAK mounted. Thanks.
