Mine are attached to the bund via Velcro and sit just below the chest armor. They are positioned on either side of the ribbing. I have small foam "blocks" inside the pouches to simulate stuff on-board.

It's a part I picked up from DJ on eBay. It was cheap and it looked really closer than the old one.
@ Elwyn
Yes, if I knew for sure it was permanent. There could be a variation or alternate part so I don't want to commit just yet.
Nice job...looking really good! Plus, great work on some lancer upgrades. Flight suits can be kind of baggy but sounds like you have a solution. Beware of zippers and pockets showing too. Your shoulder bells could be trimmed back a bit for your fit. Looking really good though!!
Your costume looks great and pretty much complete. Nice work! I would trim the shoulder bells back a bit for your fit. If possible, try to lower your belt a little on your waist. Also, make sure you paint the chest rectangle grey.
Edit: The scope also has a 35mm film canister glued on to give it more body.
I grabbed a few of these little SWAT pistols over the weekend. Wal-Mart has them for $6 now and the electronics inside and scope alone are worth it.
