"Halo" Covenant weapons racks.
I modified the weapons in the same manner as the ones I used for my Grunt Mules by removing the posts and relocating them along the dorsal line to better fit into the racks (the smaller pistols on the bottom had posts added to them as they did not have them like the rifles do). In the game, the weapons are stored laterally but the racks in the game are wider than the toys so the weapons do not fit properly when placed in laterally.
I still need 2 smaller weapons (either Manglers, Plasma Pistols, Disruptors or Pulse Rifles) to fill the empty spaces in the lower center racks but do not have any more spare Covenant weapons at the moment.
