Ranch hand peep source

[Clint S]

Was hoping someone can point me to a source for a peep upgrade on my newly purchased ranch hand (marbles seems to be the most popular)
I'm on dial up and it takes forever to go through the many threads and links to try and find any info.
Any restrictions on such an item coming across the border?
Thanks
