When out in a remote area this seems like something that would be a good idea? Most rifle parts are fairly cheap and easy to come by at home, but maybe not so much in Africa? Firing pins, extractors, fore sight blades and hood... I'm just wondering if anyone has a kit like this for their rifle and if so, what it contains? I've read that things like extractors can be a nightmare to source for the locals? As such a cheap but possibly very useful item I'm also thinking such a kit would be a nice thing to leave behind at the end of a hunt if it may help someone out one day?
