M70 stock replacement?

[Gennette]

Hello im new to the site and have a question that may be basic but no one knows much about these things. So here I am.
I am taking my M70b1 and installing new black stocks and grips on it.
Mainly I want to put a holo sight on it and trick it out but save the wood parts so I can put it back to original if I want to.
I already put the forend parts on but now im stuck with the stock. Id like the ajustable Ar style.
The m70 doesnt have the tang like the other ak's right? So your average replacement stock wont fit. Or am I cluless? I havent had it off to look yet either.
Please enlighten me as to what stock I need to look at and if a folder is an option.
I know most guys dont appreiate taking off the wood but Im not burning it or anything so be easy on me.
Thanks
