That looks pretty bleep cool and looks like it eliminates my chief complaint about the VZ58 - the squishy trigger pull.
Kind of pricy, though, at 300 bones.
Anyone who’s had this done, please let us know how you like it!
You can do your own over-travel stop. ForcedMarch used to offer for about 1/2 that (check stickies) but requires folks to send who rifles now after some reliability/safety issues with just trigger pack. The Zendl disconnector/gremlin buster is also supposed to result in improved trigger pull, but I haven't tried. The take-up is entirely to do with the disconnector and sear engagement/space between the disconector nub and the sear leg. Easiest would be to adhere shims to sear until you're happy and then have single shim permanently attached... Polishing/adjusting sear and striker interface and sear leaf spring is primary determinant of trigger pull.
Of course all of this is potentially dangerous, so would make any modifications to spare parts or have spares on hand before diving in...
IIRC, the CNCW/Bonesteel steel trigger group also advertises some improvement on take-up and over-travel.
