it's this weird clamp fit, you cannot mod this mount (o-ring for example) since it's literally just the internals being clamped in place by the top and bottom case pieces. very stiff if you're into that
Plate mount stabs and they are very tight fitting, no bandaid mod needed. They also appear to be pre-lubed, but I just got mine and did a quick inspection, no testing yet to find out if it’s any good.
