Hi everyone, I have a few questions about a gun I have been given as my knowledge about historical guns isn't very good.i beleave that it started life as a military Rifle although now it just has a 12 bore shotgun barrel on it. It has 1886 stamped on the action. I wondered wether it would be feasible to turn it back into a rifle as I fancy making a stock for it myself and having it with open sights for woodland stalking. So can you still get barrels for this action and if so what caliber would it be and we're could I get them from? Any other info would be much appreciated. Cheers. Attachment 65077
