Man, I'm gonna have to cobble-up one of those for finishing: best solution I'd come up with for my surroundings has been hanging them from the garage ceiling by a thin wire attached to a screw in the buttplate screw hole. Not very satisfactory, as can be imagined.
It's also nice to see that I'm not the only one around here, building rifles inside the house.
PS: Thanks for the heads-up, Norm!
