Has anyone had experience with this AK-47 style of rifle? I was at a match yesterday and one dude was bragging that this is the ultimate AK-47, the SA M-7, built by Bulgarian standards and built in Las Vegas, NV. Milled receiver, hammer forged barrel, forged internals, choice of wood or synthetic stocks. I would like to find an excellent 7.63x39 rifle to shoot, semi-auto of course. Thanks for any info you can share, Stan in Southern New Mexico Territory.
