Steyr AUG Auction
There is a current GunBroker auction with photos of two Steyr AUG sets. This auction is for one of the AUG’s and an FN FAL 50.64 (one of the folding stock “para” models). The AUG’s have a lot of accessories including the 9mm conversions. Below is a quoted list of items with the AUG in this sale.
I don’t know anything about Zeigler cases, a quick internet search came up with a coffin (shown below) and some air cargo containers. I also found Ziegel brand cases that look pretty much the same as those in the auction. Check out the auction here.
