A shame though -- I definitely agree that they look better deployed and it would be nice to be able to display them that way. Or even for play value, it'd be nice if we could play with the toys with their weapons deployed.
I watched peaugh's DOTM Shockwave review again, and at 6:19 he locks the mechtech weapon in deployed mode.

As far as I know, all the voyager's mechtech weapons should lock. (I only have optimus' at the moment and that one locks fine.)
