Brownells has detent balls in sizes ranging from 1/16 (1.6mm) on up to 9/32 (7.1mm). They have a kit with 20 of each size at around $100; their minimum sale is a pack of 20 of any one size for about $16.
They also have "E clips" also in a kit ($115) and with packs of 20 in any one size at about $16.
Actually, my first stop would be the local "big box" hardware store. They often have that kind of stuff in trays in the hardware section. I doubt that the maker of that sight used anything but off-the-shelf stuff so those parts should be available. You might also try a gunsmith shop if you have one that does much custom work.
