Possibly the worst modern rifle (dollar for dollar) I've had any experience with is probably the Golden Eagle (affectionately known as the Gilded Turkey by those familiar with it) this was the epitome of a polished turd.
The Cooey Model 71 was a Canadian-made winchester derivitive which took the post-64 Model 70 and cheapened it even further. It was cheap, homely, and poorly finished but was usually surprisingly accurate.
The Midland 2100 was a Parker Hale effort which used a crude Mauser-like receiver which was fitted with a Springfield bolt. Crude, clunky, and unattractive, it should never have been made. GD
