Yeah, I had noticed the same thing. $200 more for the whole rifle in 7.62, but 5.56 conversion is only $50 cheaper than others. So doing 7.62 with 5.56 conversion is $150 more than a 5.56 with 7.62 conversion. It ended up not mattering to me, since I wanted a 5.56 with the future option to go 7.62. But if you're looking for the 7.62, that changes things.
Ultimately, I don't know why I'm posting, because I can't share anything new. I just like seeing my own typing I guess.
