interesting
I've seen a handful of those rifles just lately, but everyone was a beater.
DOn't know about the durability or reliability of the 170, but a pump .30-30 would make a fair utility rifle. Ammo is common, a moderate increase in punch over x39 ammo, and more easily scoped then an SKS or a traditional top eject Wincherster.
Supposedly, they made some carbine 170's, but I've never seen one.
