Are you talking about a complete, assembled and functioning trigger assembly taken from a launcher?
..or a new, complete, assembled and functioning replacement trigger assembly that has never been mounted on a launcher? (Assemblies than have never been mounted usually have no take-down pin hole and must be drilled out by the user. (I found this out the hard way a few years ago while doing a build for a friend - I actually miss-drilled the hole and had to find a new assembly for him.)
(some Bulgarians replacement assemblies from the stash.)
..or are you just talking about a bunch of parts in a box?
