There is no such thing as differnt 7.62x39 bolt. I studied Colt before drawing my own 12 years ago and have since made more of these things than anyone on the planet including Colt. The Grendel/Beowulf bolt is the industry standard and is in fact a 7.62 x 39 bolt.
The thing referred to as a 7.62x39 bolt is nothing more than a 5.56 opened up. The extractor geometry is wrong, but they proliferate in the internet as they are a cheap way to get something to fit.
