I have Two Steyr LG 100 Barrels that came with my gun when I bought it the guy told me that one is a BSA the other is a very good German make but he could not remember, Both are covered in a Plastic/Rubber type coating and both look as new condition. Black Barrel is a .20 with a removable threaded end piece. Grey Barrel is a .22 with a finisher which is 1/2" unf thread. I can never see myself having a use for these as as the gun came with the Barley Twist Barrel. Could someone who knows about Styer Barrels give me some info on them and what price could I ask if I were to sell them. Gary.
