Thanks for the response.
You're right, I totally am just learning about it all - and admit have been confused along the way a couple of times.
It's a whole new language to learn.
Part of that confusion has been the whole ar10 and ar15 thing as well. I gather from your post that AR10 is for .308? But cannot be used in the Norinco.
In my previous post I mentioned I thought there were adapters available for the LAR15 magazine. What would they be used for?
