B square adapters - B-Square Air Gun Adapters & Risers - 3/8" to "Weaver" Adapter (2-piece base), Blue 17025

I placed an order for two sets of mounts to change from 3/8" dovetail to weaver mounts on my 22 winchester magnum. When I received my items, the screws were rusty. I ended up removing all rust and applying 3 coats of blueing.I think B Square should have done a better job to prevent rusting.
