guys,
see my post here:
ar15.com/forums/topic.html?b=3&f=118&t=163703
my just-arrived-in-the-mail KAC single point mount won't mate with my recent production bushmaster lower receiver. it would appear from a follow-up posting that the hole in the BM lower is "out of spec" by a few thousandths of an inch; in combination with the KAC mount (which is similarly oversize by a few thousandths) assembly is not possible.

I had tthe same exact problem, but used a lil' lube and BFH. That did it. When I pulled it off, only the finish was worn.

I hused a needle file to take the finnish off the lug. Once down to bare alluminum the fit was perfect.
