In .22 Long Rifle caliber, this very unique double rifle is built on a frame even smaller than the .410 frame. Each gun is custom made, with many upgrades and engraving options available. Higher grades have a MRSP from $30,000 to $34,000. NOTE: A few custom made-to-order models in various centerfire calibers have been built in the past, with very limited production. Values are estimated to be approximately 50 percent higher than the rimfire model.
