I have an LR308 with a Krieger barrel and would like to have the receiver matched up to ensure the barrel sits squarely. I've seen tools to do this with AR15s but nothing for the AR10/LR308. I'd rather not spend $500 on a one time use setup but I certainly wouldnt be opposed to paying a smith to do the work. Anyone know of either a tool or a smith that will square up the receiver face?
