Re: AR-10 Upper reciver vise block?
if its a flat top of anykind, you can improvise. its not for everyone, but I never had any problems using this method. I use a press,(one could use a large vise too) some fitted oak or maple pieces of wood(3/4 inch),for the bottom in between the lugs and across the top, and then some 1 inch thick steel plates.to support the wood. works great,especially in a press. not for the average joe.
