Ummm, But IF you were to butcher a 1885 BOLT...Let me cipher on this.... It wouldn't likely be shootable, Not even otherwise functional, probably, But if you were to cut off the bolt handle and fashion a new one for up front...

How much cubic money you got to ruin some good parts for no good purpose, whilst keeping your 1879 intact????

I still think the EMT and some Hollywood magic is the best option for display.
