If you want excellent customer service you shop at DonnyFl. I recently got a Leshiy Classic and it came with an adapter for the 350mm barrel so that you can use a moderator. It has three small grub screws to hold secure it to the barrel and the one I got was missing two of the screws. Yesterday morning I emailed Donny about the size of the screws since it was one of his products. Today I received an envelope with three new grub screws. And that's why I buy from DonnyFl every chance I get.
