Been less than a day since last post, i know! I got around to opening my packages after work.
First off, the package from Galactic Armory: one GORGEOUS resin cast an a visor im leaving in the bag until its time to tint it blue out of fear of messing with the finish inadvertently

After that, some miscellanious packages, and besides for a noble 6 fig, master chief helmet and a couple soft goods parts we'll get into on a later date, these guys showed up:

They look and feel about how i expected, I'll get to modding and working through them once im a bit further in on the build. the MA40 is missing the little shot counter that slots to the tiny top rail, obviously thats needed at the end of the day so i did a bit of hunting. I found this model for an MA37 with some rail adapters: MA37 Ammo Counter - NERF - Halo - Printable 3d model - STL files .
Is it for the MA37 and not the MA40? yes. Will it do the trick for this? we shall see. I've sliced it up to print between some armor parts.
Speaking of printing armor, I've currently got the side back/kidney plates on my printer as I type this, and with any luck this old bed slinger will have them done in a little over a day. I have a couple more parts for the torso that i'll be printing after this, but before i continue to the arms I'll be turning focus to the backpack so i can start figuring incorporating the rigging between the two as I work on getting the rest of the armor pumped out.
