you could add a 22lr action and barrel with a custom trigger it sure would look pretty , maybe a 223 make it bolt action go 308win or 30-06 , 6.5 cm or 6mm creed , you got a lot of choices what ever you like could even cut the stock and make the cheek rest adjustable with a adjustable butt plate add piping to it and make it a self contained water fountain fixture , or better yet a pez dispenser that would be cool to see that pics . good luck what ever you decide to do with it . maybe a fire armed themes lamp set ?
