Actually, a Lee Enfeld or a Mauser, or for that matter an AK47, makes a great club. Their all made of solid hardwood and steel, which does a great job of breaking open someones skull without taking any major damage.
It's the frigg'n AR, G36, etc polymer guns that crack and break when you smack someone in the head with them. I've seen people crack the stock on an C7 (the Canadian variant of the AR15) just by dropping the damn things on a rock. How's that for durability?
