I need a sight insert caddy or two. In the past I used the hinged plastic type light a fishing fly box but the never seem to hold up to my gentle handling. Looking for replacements. Anyone tried the one from MVA for about $60? Any other ideas?

This is an improvised one using a mint box with magnetic strips to hole the inserts. It also works to hold an extra rear sight disc. A couple of times I got to the range and discovered I left the Hadley adjustable disc on a different rifle back at the house. Now I have ordered a second Hadley to resolve that problem.

The box and magnets is 108g or almost 4 oz. I imagine the MVA caddy is less than half that.
