Hey Folks,
Long time no posting. Long story short I have a 308 barreled action I purchased off a friend. I believe its model 11 VT. Any way I have plenty of 308s laying around. I was looking to convert it to a 7.62x39 and use it as a inexpensive pinker.

I know I have to change the bolt head or extractor(one of the 2). But my question is it "safe" to just use one of those chamber adapters in the factory barrel? I have seen mixed reviews on them. Or am I much safer just to purchase a prefit 7.62x39 barrel and go from there?
Any experiences and other suggestions would be helpful.
Thanks!!
