Nice work on the scope mod. I'm tempted to try that with mine now.
I think Trooperbay has the S trim and neckseal. I picked up frown mesh at the Train Shack hobby shop on Hollywood way. Cut down spray painted black and double layered in with E-6000. I picked up my Aker on Amazon. Ingrid has squirrel fans and sources them locally if she's out. I'm still hunting for a new Stanley bin myself.
As soon as that armor arrives you're going to have your hands full! You're looking very organized though and I'm sure you'll be fine!
