good complete Nylon 66s, with both sights, solid stock, most of the bluing, and fully functioning are in the $225-250 range....shooter quality guns. So $175 seems about right.
Yeah as crusty and crunchy as it may be, you won't wear it out. Shoot the crap out of it, super little lightweight plinker rifle, with decent factory iron sights, clean it up with a field strip only, DON'T OIL IT, RUN IT DRY. Blaze away and these guns LOVE Remington Golden Bullets....no kidding....they shoot great in these Nylons.
