Unless I completely failed at reading the article. They are adopting an AR platform chambered for 7.62x39mm
Been there, done that. Not exactly a problem. They could just go to POF and get some.
You are reading correctly.
The hitch and expense comes from the theory that they can use interchangable barrels, bolts and magazines to switch the same platform to 5.56 when necessary for NATO requirements. Bigger problem.
