Had a look at an online at a Russian retailer selling various shooting kit.
They have a Molot Vepr 12 AR adaptor listed at 2500 roubles. That is $76
E-mailed them and they offered it to me for $130 plus $70 for shipping ( which takes 3 weeks, but more about that later )
I have e-mailed back asking why the price almost doubles for overseas customers and pointing out that the Post Office charges $30 to post airmail to Russia.
It looks like they have simply DOUBLED the cost of the item and doubled the shipping.
Oh, and 3 weeks ? Sounds like surface mail
