Ed2000,
I own one of the SAR3's, and it has been pretty good. I haven't shot it extensively, but have put a few hundred rounds through it and checked it pretty closely with no problems. The only complaint that I have is that it really dings up the brass, putting such a dent in the side that it is not reloadable. Therefore, I buy cheaper South African or Russian ammo to shoot in this rifle.
Being an AK, it is not extremely accurate (as compared to my Remington 700 or even my Bushmaster), but with the open sights it will shoot 3" to 4" at 100 yards. I am not an open sight guy, so that impressed me. I have the Kobra red dot sight that I haven't got figured out yet that should make it more accurate for me. The cheaper ammo may be part of the reason that it is not as accurate.
There have been complaints about the SAR3, that it had problems with the hammer and that magazines are hard to get. I haven't fired it enough to know if the hammer is going to be a problem; the magazines that I use I got through interarms for a reasonable price (E. German).
For the money I paid (just over $300) it was a good purchase. I don't plan on varmit shooting with it, just home defense. It seems to be a good, dependable weapon that allows me to use the same ammo as my Bushmaster if I need to.
