Another rifle that you probably no doubt expected to see on this is the AK-47. Technically, the AK-47 can be either a selective fire or a semi-automatic only version. In the United States for civilians, most AKs sold are semi-automatic only for legal reasons. The AK-47 usually fires the 7.62x39mm round, the same round as the SKS, and comes standard with a thirty round magazine. The 7.62x39mm offers superior power to the 5.56 of the AR-15, and is therefore a superior round to use for hunting larger game. Contrary to what many people think, the AK-47 can indeed be used as an effective hunting weapon if necessary, and it can also easily be used for home defense or tactical use as well.
