Disassembly of the 2 claws when the spacer has been put into place is a pain in the ass, but once I got it apart fixing the lead in of that taped hole was just a matter of using a scraper and running the supplied bolt in from the rear and repeating as needed. Timing the buffer tube didn't go quick either, when I found the combination of 2 shims that was almost right I needed to remove a bit of material to get it right but for some reason a file only removed the molding marks on the shims but a medium india stone worked, go figure, YMMV though (medium india stone was the most aggressive stone I had handy). I took my time timing the disconnector that came with the JP trigger but I wasn't so impressed with it's quality and put the disconnector in from the bushmaster LPK and it was timed perfectly with no modification, wouldn't you know. Unforchently these factors led to the build lasting into the morning (along with some reloading I did) and I missed the Houston New Years Eve shoot at the impact zone :( .
The push pin is pretty damn hard to push in, at first I couldn't get it into the left side of the lower without using a dead blow hammer but now I can push it in via my thumb but it's not easy, taking it down still requires a push pin tool and a hammer. It's getting easier to take down but I don't know how long it will take to being where I'd like it to be.
