noticed a variation on my two long arms. both from the same case, but each have mold differences on the weapon. longarm 1 has no stop pins for the hook or inside the boom arm to prevent the hook from folding all the way in and getting stuck. wich i found difficult to re-transform. longarm 2 has stop pins on the hook and pins INSIDE the boom arm to prevent the hook arm from folding to far and getting hooked up and stuck.
