Hoppdoc,

NE member [url=http://www.bpgunsmith.com]Brian Perazone[/url] has posted pictures of a 22 lr double rifle that he made over here in the past. You could talk to Brian and check. He is a really nice person to deal with. I don't have any double rifles but I bought a Mauser custom rifle from him and am very happy with it.

Good hunting!
