The RPK by both the Yugo's and the Bulgy's are top notch. The Yugo does not have a chrome lined barrel, but it is no big deal. I had a few in Asscrackistan that I beat the PISS out of and they kept right on running. The Bulgy is milled and they are BEAUTIFUL! If you want a shooter and wall hanger, this is the way to go. The Yugo has function but not so much beauty.
The run on AK's is based on Obama getting elected. We have about 100 guns on back order right now that are AK's and AR's, mostly AR's. We have several types of AK's available and if you want to know about them go look here:
