I wish I'd bought one of those Izzy HB kits when I was in high school. Then again, I wish my DSHK kit hadn't been stolen, too.
I have 2 stg58's. One with a G1 barrel and the other with a Styre.
I have a few Steyr kits in VG-EXC. condition. Most are matching #s. What are they going for now days? $275-300??? Haven't looked at this stuff in years.
