Silicone treated and seem to cost about the same as most others, e.g. six for $33 Amazon (56").

Bore Stores.
They use to make custom sizes. You will have to email them to find out.
They do stretch a little.

Those ones you listed won't stretch enough to cover a scope unless its a hunting type of rifle with a.small scope.
