I appreciate your response.
If "clean up" is important why not use a chrome lined barrel, if accuracy is important why not use a "select" match grade barrel.
So, "everything" is a bit of a compromise; unless money is no object of course.
I'm looking for relative accuracy, not going to be using it for bench rest competition.
BTW - What quad rails ?
The Burris XTR Tactical rings do not use inserts like the Zee rings, but are much wider than the Signature rings.
