USPS finally got their stuff together; the spacebars arrived yesterday.
Will probably post pics later, but
oh my goodness these look so nice on my Leopold. Feels great, too. One thing to note is that it took a couple tries to properly seat my blue one on the stabilizers--they rattled like crazy the first couple of times, and on the third time I seem to have got it right.
Anyways, good stuff. The Leopold's plate-mounted "thock" works so well with the deeper tone of the PBT spacebars. Love 'em, and thanks again Matt3o for doing this. I just need matching ESC and/or CTRL sets to do them justice.
