I saw someone made a real nice floor lamp out of an old worn out rifle. They screwed the buttstock to a wooden disk to hold vertical and ran the power cord through the bore . they mounted a lampholder and shade in the muzzle . looked really nice.
I build driftwood furniture,,,
I've done this with several long guns,,,
And you don't have to demage the barrel to do it.
Or make a one-rifle display rack,,,
Mount a couple of inexpensive lamp sconces,,,
And you have a very nice heirloom decorator wall lamp.
