RE: How accurate are AK47s
I had a saiga sporter in 7.62x39, with the scope mount. Biggest POS gun I have ever owned in my entire life. It sure didn't need the scope, I could have done just as well without the sights all together. My SKS was WAAAY better in every aspect. I have shot a few mac 90's or what ever they are that were not too bad. I still wouldn't hunt with one though.
For the same money I paid for the saiga you could get a H&R single shot rifle and it would be much more accurate and you would have the option of swapping barrels from different centerfire rounds to shotgun barrels.
Also keep in mind to check your local laws. Many prohibit Semi Auto rifles, rifles of a certain length or type and how many rounds it can hold.
If money were not a concern I would suggest an AR style weapon chambered in .308. This would be an excellent all around weapon.
