Everything you may want to know is at http://www.ak-47.net I own a SAR-1 (7.62x39). The Sar-2 is 5.45x39, and the SAR-3 is a .223. From the manual SAR simply appears to stand for "Semi Automatic Rifle". What do you need to know about them? If you're looking for prices, check out http://www.aimsurplus.com The only danger in ordering a SAR was the improperly hardened trigger group parts (seems to have been corrected), and the occassional canted front site tower.
