I just had a .308 Enfield Ishapore barrel installed on my large frame Martini and had the rim recess cut for .307 Winchester. The dual extractors work like a charm in this setup. I'm using the original Enfield sights. The Enfield fore-end screw hanger is a barrel band with a threaded nut forward of the rear sight, a little long for a short sporter fore-end. I'd like to hear recommendations for a safe way to attach the fore end. The barrel is too thin in my opinion to risk drilling it for a threaded hole or for a dovetail for a hanger.
