the duo ring mount is a 3 part system. it was meant to be a quick release. you will need to find a base and a base adapter. its a wacky set up. Cayugad has the one piece weaver base. that one is the easiest to use but hard to find. before that version there was in a 2 piece base and weaver flat rail version. the one Falcon has a link i had at one time. i forget who made it.the New Englander was a tough gun to shop for when mounting scopes but if your patient you can find the mounts .
