If they don't malfunction in the field ( and they haven't) then I'm happy!
But on the same vein, I've never encountered a plethora of other problems I keep hearing about...extractors on m700s,bolt handles coming off, etc......so maybe I've just been lucky ( that hasn't carried on to other facets of life neccessarily!)
Long as I'm on it, I just found and bought my wife a 722 in .222 in minty shape, and it shoots so well, I can see where the cartridge got its reputation...
