Got mine last Friday - I had ordered seven of them (six to open, one to keep MOC) - thankfully they put them in a nice sized box, so they all arrived in great shape.
I also am thinking they modified the hands on this release compared to the single carded figure, with the exception of the garden-blower, I've had no problem getting the Armory Pack figures to hold the various weapons included in the pack.
Considering that they included all of these same weapons with the SDCC 6" version of the figure, kudos to Hasbro for scaling those weapons down and getting them into the hands of 3.75" collectors as well.
