I had a chance to shoot a .308 MAK tube gun over the weekend and fell in love with it. I already own an XLR chassis based center fire gun, so I don't really need to build another one. I had planned on doing an AR based 22 build, but if I could find a tube gun kit I'd rather go that way. What is out there that will accept a common .22 action and barrel? I'd prefer a repeater, but single shot would be ok. I don't want something that requires some bagillion dollar unobtanium action / bolt / trigger assembly.
