It appears as if I have purchased an LVT. Does anyone make one piece 20 MOA bases for these rifles? Does the 57m share bolt hole configuration with any other rifle? Anschutz?

Thanks in advance.

Cooper uses a picatinney rail uses when test-firing their rifles but for the life of me I cannot recall which brand. Give them a call (406-777-0373), I am sure they would be glad to tell you, then you could contact the manufacturer to see if they make a 20 MOA base.

An alternative would to use Warne bases and Burris Signature Zee rings with the +.20 inserts.

No idea on the bolt hole configuration question.

Cooper shows them for a 57M on their web site. I would call these folks. Shows a 20 moa for a 57.
